If you compare this to the above Tom's benchmark selection you'll see that this result puts my 8500GT just above a x850xt and 5fps quicker than a 7600GT and im using a e6420 cpu @stock speeds which is 800mhz slower than the X6800 used in that review (the rest of my PC is on par with their PC, Asus P5N-E, OCZ 2gb ddr2 800)!
This to me shows the great potential in the 8500GT if other manufacturers go beyond the nvidia reference specs as gainward did with their card making it 600mhz gpu\1200 gddr3 mem\passive cooler for the same price as the bog standard 8500gt (£60).
Infact Gainward also have a 8500GT with the memory clocked to 1400Mhz\GPU 600Mhz for the same £60 as my card but this card comes with a fan so I went with the silent option instead (little less speed but MUCH less noise).
Aye but do you want to pay for a new graphics card to get 5 fps difference on a game that is several years old now? It's not worth 50 quid to get comparatively low gains and that's only one game, if it fares 5 fps better in oblivion I might be interested. It seems like a ludicrous waste on your chip to use such a low end card.
