My CPU is Intel Core 2 Quad Q6600 G0 Stepping (2.4GHz 1066MHz)
My MB is ASUS P5N-T Deluxe 780i SLI Socket 775
TBH my MB is not very good. I have 4gb ram sitting in the draw, it is supossed to run 8gb but it just causes it to crash unless I lower the speed of the ram in the bios. Also overclocking the cpu is not possible at all, it just causes the PC to crash if I try overclocking the CPU at all.
It's a little past time to ad another card. You can add a GTS 250 to SLI, but with new cards coming out next month I say you wait a few more weeks (you've waited this long) and overclock your CPU. If you could overclock your CPU Id say get a GTX 560Ti or a Radeon 6950, but at stock clocks I'd say stick to a 6850 or GTX 460. It depends on the game but I think that would be a good match for your system even if they would be hampered by your CPU in some games. There isn't a point in getting anything more without upgrading your platform, though if you're going above 1080p then perhaps a GTX560 or 6870
Hiya, MSI GeForce GTX 570 coming in at about £260 tho a little more Asus GeForce GTX 570 DirectCU II would be my choice as it runs much cooler and with the price droping now mabee u can pick up at great price. GL
I have a p5n-d and was using a q6600 B0. That thing would not go past 2.8 ever. Replaced chip with a Q9650 and I got it at 3.8.
Right now you cant go wrong with video cards. To upgrade a 9800gtx you want to go big. Its better to spend a lot and have buyers remorse and a kick ass system, then spend a little and have buyers remorse because you only got a 5-10% lift.
I would go 560 or 570 if you want to stick to nvidia, or a AMD 6870 or 6970.
