hi all, I'm planning to upgrade my system. I have a q6600 quad core, mobo is gigabyte ga-p35-ds4. Graphics is evga 8800gt, 512 mb. It's only pci-e, and so is the mobo. I want to keep the mobo, and upgrade the cpu and graphics. I'm looking at an evga 9800 gt with 1 GB memory. It's pci-e 2.0. So the mobo only handles pci-e, but it does take the new 45nm intel quad cores just fine. I'm going to get the q9650. I care more about the 1Gb of memory than the pci-e 2.0, but: how well is this going to work on my old mobo? Thanks! PS: My PSU in an Enermax Infiniti, 650 watts.
