Testing Results
just a compilation of my testing results to compare the cards
we have
5870
5870 crossfire
480 @ stock
480 @ GPU 900MHz, Mem 1109MHz, Shader 1800MHz
tests carried out on:
Intel Extreme 980X @ 4.2GHz
OCZ Blade 2000MHz 8-7-7-20-1T
Rampage II Extreme - Watercooled
Corsair HX 850w
Intel X25 160GB SSD
i dont have many games installed at the moment...
i did do the comparison on MW2
but mw2 gives 91fps on all of them solidly with vsync on or off
the settings used for all of the tests are the same except where stated.
every game running at max settings except where stated.
the resolution for all testing was 1900X1200
i used Fraps to record a 60 second benchmark and used the same mission in each game to take the benchmark.
Splintercell Conviction - very console orientated port. not too brilliant for benching and with an obvious cap on fps.

the clocked 480 takes the lead in a dramatic way here and felt the smoothest experience. the colours seem a little richer and more vibrant in this game too with the nvidia card.
Dawn Of War II - generally favours single GPU. the stock 480 kept on getting massive max frames on this test. i did three runs at stock to make sure and it happened every time. the overclock seemed to add consistancey to the FPS. the crossfire did very poorly in this test.
GTA IV - the Lost & Damned this has been pretty much the hardest to judge. the game is poorly coded for pc and doesnt play well on max settings. i had to take aa and af down to the second lowest settings but kept view distance on max. again the 480 had the most consistant framerates both stock and clocked. crossfire performance was shambolic... again
Just Cause 2 - Nvidias current posterchild, i felt reluctant to run this as the ATI cards only run to 60fps, whereas the nvidia cards are uncapped. this i found very strange. nonetheless, the results were fairly tight together
Bad Company 2 - this contains some quite strange results. after compiling the charts i realised that i had benched the 480s with the AA set to 32X
this throws off the results slightly, but i plan on redoing them soon and ammending the charts.
