Mah you don't need 2GB od RAM, 1GB is enough, you only need that much for computers that run servers or some demanding tasks.
As for good PCI-E motherboards I found this: http://shop.store.yahoo.com/directron/a8nslid.html
Praet0rianIm looking into a PCI-E mobo. Anybody know good ones? I'm probably going to get a 500w PSU, unless I get a different Graphics card. I would get 2 gigs of DDR2 if AMD were compatable with it, but as you know its not so Im just getting a gig DDR. (2x 512)
I'd recommend the MSI k8n Neo4 for your PCI-E mobo. If your looking for a good PSU, I would also recommend a Vantec Stealth. As for the question of the hard drives, what I usually do is have a small but very fast one for my system drive. Raptors are very good for this purpose. Then after that, buy hard drives as big as you can get them, don't bother with the smaller ones, just get as many 300Gb HDDs as you can possibly fit in your case.
For a PCIe motherboard, I'm myself partial to ASUS' A8N-SLI Deluxe. Huge longevity/upgrade potential, also. As far as PSUs are concerned, you're not likely to go wrong with a 600W OCZ. 2GB of RAM is fantastic. If you have use for it. Most games won't make that much of it, and you'll generally wind up wasting your money (particularly on a performance system, which more or less demands using only two DIMMs, forcing you to go with 1024MB sticks--much money). DDR2 is, quite frankly, overrated at this point in time. Morlak's got the right idea on HDDs. A 74GB Raptor for your OS, backed by Seagate 7200.8's (which I haven't actually seen in use; they might not be all we're hoping for) for data should do nicely. SATA is all good and well, but still has a lot of compatibility and support issues and most SATA drives (Raptors being the biggest exception) are actually standard IDE drives in a SATA wrapper. The 6800GT is a better buy than both the standard and Ultra editions of that card, and should be the one you go with. I've heard good things about Gigabyte's card (just be sure that you have enough clearance above the card, as the bulk of it's HSF unit sits on the backside of the card. Leadtek's seem to be having QC issues, and ASUS is doing enough oddball stuff to make me shy away from them. Can't speak for any other makes, though I've heard good things about eVGA.
I ony have 1Gb and its sweet. Also, will that processor be enough for you, it will today, but the future?
