I'm looking to upgrade to either a GTS250 or 9800GTX+. I want to make sure they are compatible with my setup and that I will see improved graphic quality and performance over my current cards. Will the above single card offer significant upgrade over current SLI cards? Below are my system specs. Any input is greatly appreciated. Thanks.
Microsoft Windows XP Professional x64 Edition
Asus A8N-SLI Deluxe (3 PCI, 2 PCI-E x1, 2 PCI-E x16, 4 DDR DIMM, Audio, Dual Gigabit LAN, IEEE-1394)
2X NVIDIA GeForce 7950 GT (512 MB) SLI
AMD Athlon™ 64 FX-60 Dual Core Processor @ 2.8Ghz
