I currently have a Core 2 Duo E8600 3.3 gHZ processor and an 800W power supply. I'm looking to upgrade my graphics card from a 450 GTS to a Radeon 7850. I know my motherboard (EVGA 122-CK-NF68 Nvidia NForce 680i SLI) supports the card, but I was told that if the CPU cannot handle the card, it isn't worth it. I know my processor is outdated, so how can I tell if my processor will be able to handle the new card?
