The performance of the 5750 is lower than that of the 5770 to the tune of 20-25 per cent which is a big step down for a relatively small reduction in price. On the face of it, the 5750 misses the mark and we'd recommend the 5770 to any gamer on a budget that won’t stretch to a £199 5850.
Better for casual gamers than serious players?
This is only part of the story because we saw something rather interesting when we added Nvidia GTX 260, GTX 280 and GTX 285 cards to the mix. The performance of the mainstream GTX 260 is essentially identical to the 5770, which has forced Nvidia to drop the price of the 260 to £125. The GTX 280 has been replaced by the GTX 285, which can be bought for £219. But even at this reduced price, it struggles to comprehensively demolish the 5770, which is much cheaper. More worryingly for Nvidia, the 280 gets trashed by the slightly cheaper 5850.
We have previously run 3DMark Vantage on an Asus Matrix GTX 285 using the same Core i7 system and this £289 graphics card was beaten hollow by the £299 5870 and also by the £199 5850. Our view is that you'll struggle to play the imminent crop of DX11 games at high image quality settings on the 5750, and the 5770 isn’t much better. We blame the 128-bit memory controller for this failing as the 4890 is significantly better. If we could have the power saving features of the 5750/5770 combined with the performance of 4890 we would be happy.
As things stand, we can't recommend the 5770 to serious gamers - we suggest the more expensive 5850 instead.
The Radeon HD 5770 comes close to being a superb graphics card, but AMD has throttled its performance. We suspect that the company is trying to segment the market to leave Nvidia without a leg to stand on and in that respect it has succeeded. Unfortunately, it hasn’t delivered the mid-range graphics card that caters to gamers on a modest budget. ®

ATI cards "struggling" with HD channels in Windows 7
Nice article by PC Pro
Its good to get bad press...
Ive also read that other 5xxx cards blue screen coming out of hibernation in Windows 7... ATI - Sort it out!
no clear card for "gamers on a modest budgets?" that'll be the recession and, correct, not wishing to give Nv a leg to stand on. in this downturn they need clear pricing and clear products. the low and medium products have to be significantly inferior feature wise to make the premium stand out.
all they gotta do is sort their drivers out now! something ATI were berated for yonks ago! AMD do not want this label of "bad drivers"!!!
Not touching until they fix the driver issues
Thanks for the links on driver issues above, it has been sadly informative. If you believe the ATI forums (obviously the number of unhappy users will be high, as happy users don't tend to post) the driver stability has some way to go, especially under Windows 7.
Perhaps in a couple of months.
A 5770 Crossfire will also convert a lot more electricity into noise and is prone to the microstuttering effect. Both is rather undesirable. Additionally the 58XX have better overclocking capabilities.
Interesting to see 2x5770 easily outperforming 5850, and occasionally the 5870 as well, considering 2x5770 costs only 15% more than a 5850, and almost 30% less than a 5870. If you've got the room to spare...
Roll on 5770 X2?
