Just bought a couple of hdmi 5770's to complete my build, ive been putting them through their paces with several games and can tell you i think they are the best bang/buck card at the moment. Prior to the 5770s i had one HD4870 which was ati's best offereing for budget gaming, as you may know the 4870 has 1gb and 512mb of ddr5, i have the 1gb version and its got a 256bit memory bus, even so the 5770 has better performance with a 128bit memory bus and i think this is amazing. In every game i tested the 5770 beat the 4870 by about 4-8fps whick ok doesnt sound much, but concidering that the 5770 is only £115 with the benefits of DX11 & eyefinity and the 4870 was £135 you really can't complain. also the 5770 uses a 40nm process and even at full load on the games i tested it stayed around 48oC, Now this is a different story on the 4870, maxed out the card goes to over 80oC and i can promise you it will burn your fingers. Ive put the two 5770's through their paces too in crossfireX and can tell you that the performance is truly amazing, ati seem to use a different approach to using multi gpu's than nvidia, if a game doesnt need more fps the texture quality goes a lot higher, the gpu power gets put to better use, with nvidia's sli, it seems that more unwanted fps are thrown at the game when theyre not needed. After all 60fps is the sweet spot if youre using vsync. the 5770's keep all my games rock solid at 60fps, they dont budge even if i bump the games upto 8xaa. The version of the cards i bought are asus, and for a good reason. First of all asus are the best overclockers and even though looking at the card you might think the cooling solution looks crap, it's really clever what they've done with it, you can unclip the fan surround then the card can be made to fit in a single slot with a third party cooler, when youve changed the pci bracket of course, the fans are whisper quiet you dont know they are running, also unlike the 4800 series cards the 5770 only needs the power from one 6 pin plug, and its over an inch shorter in length. The 5770 clocks to over 950mhz on the core with ease, and the memory clocks just as good, im going to do more stress testing to see just how far this baby can go and stay stable, then will flash the bios and keep it there permanently. For people on a budget these cards are the way to go, the performance is awsome for the price you will not get better. This card is a perfect match for the qx9650 cpu. So basically your getting a card that has better performance than the 4870 with dx11 and is cheaper, slower than the 4890 but to be expected, well done asus!
