2gig of ram is perfectly fine, i believe 3 gigs is the most windows will let you play with. a fast hard drive is more important for smooth play at that point.

the e6600 is a superb processor you can overclock it into the 3ghz range easily.

cant go wrong with any of the 8800's.

Correction them most an amd 64bit can possibly work with is 3.75gig..... :oops:

sorry

Or if you want cheaper swap out your current RAM for 2GB dual channel DDR-400 low latency, and upgrade that video card to the AGP version of the Radeon x1950 Pro 512MB. This will only work until you want a DirectX 10 game.

Or for the new system you are looking at, remove the XP from your old system and use it on your new system, but go with 2GB RAM and use the money you save from not getting 4GB (and Vista) to get an 8800 GTX (leave the Ultra alone for now till prices drop), and when you have to (maybe in a year or more?) go with a 64-bit Vista and 4GB RAM. The GTX is a fair upgrade from a GTS (96 stream processors vs 128 in the GTX, whereas the Ultra is essentially an overclocked GTX for a bunch more money). And unless your running extreme resolutions (1920x1200 and above) you can probly skip SLI for now too.
