I am planning to get an 8800gtx from MSI or a EVGA brand. The Card I am planning to get is a MSI GeForce 8800 GTX OC 768 MB I have a AMD Athlon X2 4200+ OCed to 2.6 gHz. 2Gb of Dual Channeled Ram (OCZ Platinum PC2-6400 = DDR2 800). MSI K9N Diamond 590 SLI MCP Motherboard. And a Antec Trio 650 watt, 3 12v railing arrangment. Will my system be Bottlenecked with a 8800 Gtx onboard, or not.
