See this for some background: http://lists.debian.org/debian-user/2009/07/msg01216.html I'm currently considering the Intel DG45ID motherboard. It has everything I need, including Intel's best video chip (X4500ID): http://www.intel.com/products/desktop/motherboards/DG45ID/DG45ID-overview.htm The DG45ID does not support the older generation Pentium processors (4 and D), which should tell you something. Furthermore, this benchmark shows that modern Core 2 Duo cores are faster than any Pentium, past or present (see http://en.wikipedia.org/wiki/Moore's_law ): http://www.cpubenchmark.net/cpu_list.php Intel Pentium 4 3.80GHz 615/1 = 615/core Intel Pentium D 3.40GHz 900/2 = 450/core Intel Pentium E6300 @ 2.80GHz1811/2 = 905/core Intel Core2 Duo E7400 @ 2.80GHz 1871/2 = 935/core Intel Core2 Duo E8600 @ 3.33GHz 2417/2 = 1208/core The modern Core 2 Quad cores run at lower frequencies (heat?): Intel Core2 Quad Q8300 @ 2.50GHz 3553/4 = 888/core Intel Core2 Quad Q9650 @ 3.00GHz 4426/4 = 1106/core But, the smallest i7 core is faster than any Core 2: Intel Core i7 920 @ 2.67GHz 5444/4 = 1361/core If 3-D video is important, Intel's G45 doesn't compare against generation 9 and 10 NVIDIA cards: http://www.videocardbenchmark.net/gpu_list.php G45/G43 Express Chipset 191 GeForce 9500 GT 376 GeForce GTX 260 1719 (NVIDIA's drivers seem to work better now, but are still closed source.) So, I'm also considering the Intel DX58SO motherboard plus an NVIDIA card: http://www.intel.com/products/desktop/motherboards/DX58SO/DX58SO-overview.htm The DX58SO has over-clocking capabilities, if you're into that (I typically run my machines at specified settings): http://benchmarkreviews.com/index.php?option=com_contenttask=viewid=262Itemid=69limit=1limitstart=9 As always, benchmarks must be taken with a grain of salt (gram? gallon?). If you have a specification application in mind and can map it to specific assembler/ compiler/ processor/ GPU features, disregard all of the above. Also, recompiling/ redesigning your application for multiprocessing will allow for multi-core possibilities and beyond ( http://en.wikipedia.org/wiki/Beowulf_cluster ). Surfing for prices and min-maxing a modest 32-bit motherboard + CPU + RAM [+ video] setup: ~$300 for DG45ID/ Core 2 Duo/ 2 GB ~$450 for DG45ID/ Core 2 Quad/ 4 GB ~$700 for DX58SO/ Core i7/ 3 GB/ NVIDIA PCIe x16 Give Page's Law ( http://en.wikipedia.org/wiki/Page's_law ) and my personal usage patterns, I'd label the DG45ID/ Core 2 Duo as a 3+ year desktop and the DX58SO as a 5+ year desktop.

I think I bought earlier this year this same mainboard I'm not very happy with intel graphic chipsets but for the price it's not bad. I'm using it for a server I have at home and I thought I could use also as a workstation, but there was some delay in rendering graphics (when watching video or tv. The board itself had a really stupid bios, because it could not recognize and remember all of the drives I attached to the board (look for info on that if other people have the issue). As it's server I can live with that but when rebooting I need to try several time (going to the bios and checking if there are all the drives recognized and listed) regardding the video I had following situation. The machine stopped suddenly and didn't come back until next day. The next day it booted (almost normally - see above). Since then I'm not trying to use it as a workstation and it never happened again, so my suspicion is that it overheated somewhere in the graphics part and had to cool down over night. Also it came out recently that intel was selling bundled sh*t to pc manufacturers, causing disadvantage to competitors and they were sued (don't remember if the EU or in the US - I think it was the EU) Just be careful! regards -- To UNSUBSCRIBE, email to debian-user-requ...@lists.debian.org with a subject of unsubscribe.

Any suggestion on which motherboard (or motherboard type if you prefer to be uncommittal about brand) would be greatly appreciated. Thanks francesco pietra If you want a fast, single-core processor, the Pentium 4 3.8 GHz can be found on eBay. It uses a LGA775 socket, so the motherboard can be upgraded to a Core 2 Duo or Core 2 Quad (but not Core i7) in the future, if the programs you run ever get upgraded to take advantage of multiple cores, or if you want to run multiple sing-threaded programs concurrently. Once you decide on the socket type (in this case LGA775), then it just comes down to what other features you want on a motherboard, and buying one from one of the major brands (Asus, Gigabyte, etc) that matches your feature list and budget. Any LGA775 board you buy will have multiple SATA connectors on it. They usually have fake RAID, but I don't recommend you use it. Instead, use Linux software RAID. -- To UNSUBSCRIBE, email to debian-user-requ...@lists.debian.org with a subject of unsubscribe. Trouble? Contact listmas...@lists.debian.org

That machine has been around for a while, yes? Looking at the specs and a review that mentions that they would have liked to see the AMR slot removed in favour of another PCI or perhaps even an ISA, I'm going to guess this isn't what one would call an insanely fast machine. :-) Absolutely no need of multicore, rather, a single fast processor would be of use for scientific purposes as parallelized codes are rare stuff.

Any suggestion on which motherboard (or motherboard type if you prefer to be uncommittal about brand) would be greatly appreciated. Motherboard manufactures all have good and bad designs and runs, so recommending a brand isn't such a good approach IMO. Anyway, (and I'm sure that you probably already know this) virtually any board easily available today is going to make use of DDR2 memory, will have SATA ports (usually 4, but I've seen some very low end ones that only had a pair), and may require a 24-pin power supply (some will still run with 20 pin or you might be able to get away with a 20 to 24 pin adapter). Another thing to consider is PCI slots. I do not know how your old system is set up, but that board has five PCI slots. That many PCI slots is becoming hard to find on current motherboards with the average being three, perhaps four, sometimes as low as a single slot. Myself, if I had a system similar to what you listed at the beginning, I'd find one of those low-end cpu/motherboard combo deals that show up at Fry's or newegg every so often. These usually consist of a Core2 based Celeron and an ECS (sometimes biostar) board. In my experience, the Core2-based Celerons running at around 2 Ghz (or less) are every bit as capable as a P4 3 GHz, but use considerably less power and generate a heck of a lot less heat. If I needed a bit more CPU grunt, I'd get a CPU that is built on the Core2 platform that isn't a Celeron. IMO, there isn't much point in not getting a multi-core CPU. Looking at Newegg for example, a 1.8 Celeron single core and a 2.2 Celeron dual core has a price difference of 10 US dollars, and just about any CPU commonly available is going to have 64-bit capabilities, not that you have to us them. Ultimately it depends on what your budget is, what is available in your area, and how much you want the newer board to do. But unless you are going to look at a machine that is about the same vintage as the old system, you are going to have to pick up more than just a new board. -- To UNSUBSCRIBE, email to debian-user-requ...@lists.debian.org with a subject of unsubscribe.
