Benchmarks are based on the level with the worst frame rates,anything higher than 30 is smooth,anything higher than 60 is flawless. 54 on ultra is awesome.
If you're really worried about it get the Ghz Edition 7970 which performs even better,especially overclocked.
ohhh i didnt know that the benchmarks are based on worst frame rates... alright well ill grab the sapphire radeon 7970 GHZ edition, so my setup with that gpu, and all the rest of my system as stated above.. will be sweet and will be a real awesome gaming pc right? or is it really not that spectacular lol
