I have a mainboard from far far away Gigabyte G31-ES2C with Intel E5200 2.5Ghz
I want to upgrade it with HIS HD 6670 but the mainboard does not have PCIe 2.0
I know that the performance will decrease when I use it but I want to know how many percents it can be decreased
And how about GT 430 ?
Thank you so much !
 
Solution
No performance will be exactly same on pcie 1.1 and 2. Only very high end cards like 680 have only 5% decrease in performance when run on pcie 1.1 compared to pcie 3

6670 is better than 430
