your GTs are low man, try a different OS maybe

in my LN2 testing video i did pretty high GTs with stock GPU and 6.5 only

you're missing a few K

I know that, I wanted to try XP but for whatever reason coudn't boot with new bios... And no more Ln2 until december

i used W7 in the video i think so maybe give that a try also

damn December is a long way away
