Maybe I'm not the only one, but since you're comparing dual GPU cards, you should have thrown some SLi nVidia's and other ATi's, like the X2's (GTX 295). Yeah, if you have a crossfire that outperforms a lot of single cards, you shouldn't be surprised, because you have two GPUs, so double the performance (kinda). The problem would be if a crossfire couldn't outperform a single card. THAT would be surprising.
I think Chris tested it against hardware within +/- ~$50 price range, so it was a pretty fair test aimed towards his intent, which was to show that at a $220 price point, 4770 Crossfire setup is the performance leader. However, as the tests showed, that can change a little depending upon the situation. A GTX295 is
WAY above that price...
But, since we didn't see everything covered, here's what I'd like to see. Compare this 4770 Crossfire to relatively priced Crossfire and SLI setups. Such a comparison should include:
4830 512MB Crossfire (~$180)
4830 1GB Single and Crossfire (~$125 ea. or ~$250 pr.)
4850X2 1GB and/or 4850 512MB Crossfire (~$240-$260 - as low as $200 w/ MiR)
4850X2 2GB and/or 4850 1GB Crossfire (~$290-$300)
9800GT/GTX 512MB SLI (~$240)
9800GT/GTX 1GB SLI (~$270)
GTS250 512MB SLI (~$250)
GTS250 1GB Single and SLI (~$150 ea. or ~$300 pr.)
Almost all of those considerations fall within comparative price ranges, or at the very least should fall within comparative performance ranges. In particular, I'd really like to see how the 4770 Crossfire stacks up against it's 1GB cousins, the 4830 1GB Crossfire and 4850X2 2GB/4850 1GB Crossfire, as well as 1GB nVIDIA cards in SLI configurations. All of those configurations should show significant benefit at higher resolutions and detail levels due to their increased VRAM.
And please, test some
retail hardware... No more "engineering samples," including the CPU on the bench system.
P.S. There was no need to throw a GTX275 into the 4770 Crossfire review because the data for comparison to the 275 is already on record within the 275's own review where it went head-to-head with the 4890, which is listed within this review. Load up both reviews in browser tabs and swap back and forth to compare.
