I think it'll be that mobo because of the lack of PCIE 2.0 compliancy although it has 16x node. This leave me a conundrum, I can't afford new mobo + ddr3 Ram + new processor (though I will as a last resort).
Although the system is working fine, I have seen no performance increase from upgrading the graphics card to a gtx 480 from using my sli 8800gt configuration.
I was thinking the cheapest option would be a newer 775sk mobo (750i/780i/ASUS P5K SE/EPU) and then I wouldn't have to upgrade the processor & ram.
So in conclusion, would a new PCIE 2.0 (Minimum req of the gtx 480) mobo make the difference or am I flogging a dead horse and should I replace the lot.
Only 2.67 is not going to help. Getting a new mother board isn't gong to help. You'll truly need to get newer ( faster ) processors, mother board and ram..... i5-i7, etc. You have a high end card that is being held back by the rest of the system. If you can't make a substantial upgrade.... save your money until you can.
The pci-e values........ not going to make a whole lot of noticeable difference if it's 1.0 - 2.0 - 16x - 8x......... big myth to get you to think what you have is useless.... it's called marketing. Next thing will be pci-e 3.0 and 2.0 can't be utilized yet.
I hope you meant 4gig or 8gig not 6 or it won't run in dual channel mode. But anyways good for you..... "I couldn't just sit there and watch my new gtx480 underperform so I went with these:"....... made me laugh.
