i aparantly have a gigabye GA-7VT600(-L) but i dont know what chipset that is and im wanting to know what is the best CPU that will work on it. i was planning on getting a sempron 2800+ and now they have this sempron 3100+ but i saw somewhere that it wont work on my MOBO also i saw they have these Semprons models that are K8 Sempron 3000+ 64bit S754 now i dont understand i thought that S754 didnt support 64bit and it sucks because now i wont be able to buy a new cpu!
Looks like the best thing you could buy for that system is an Athlon XP 3200. The best thing(s) to do would be to either a)live with it or b) get a socket 939 board. Sempron's are socket 754 or 939 so they won't work for you.
There's no way you could get enough for any 2nd hand motherboard (especially something like Socket A) to buy any kind of decent video card, I'm afraid.
Your AGP video card will be compatible with some S939 boards still, however unless you want to look at a new motherboard next time you want a new video card, you should hold off the upgrade 'til you get some more cash together for a PCI-E video card, motherboard and S939 A64.
I've read in the forums (from a reliable poster) that those other boards cripple the AGP slot by actually running it through the PCI bus. I've also read that they are limited to a few select AGP cards (there's usually a list posted on their sites) which can be used.
Apparently, the Asrock Dual board is the only one that has "true" PCI-E and AGP capabilities. If I can find the original thread I'll post a link here.
