I have an Alienware Area-51 with a Abit AA8XE 925XE MB, 2 gigs ram, and a 7600 GT with 256 Ram. I am thinking of upgrading my video board to a "MSI NX8800GT 512M OC GeForce 8800GT 512MB 256-bit GDDR3 PCI Express 2.0 x16 HDCP Ready SLI Supported Video Card" and also adding "Crucial 2GB (2 x 1GB) 240-Pin DDR2 SDRAM DDR2 533 (PC2 4200) Dual Channel Kit Desktop Memory" for a total of 4 gigs of ram all for $260 delivered. How much of a speed diffrence will I see? Will it be worth the price? I mostly play RPG's Everquest 2, The Witcher etc... Thanks for any info..
