Hmmm that's a thought, I do know that they have been reported slower on DX9 for the 7000 series and lower tessallations than Nvidia on average so that would affect older games and new ones with heavy tessallations. I don't understand the recent belief in performance/cost for AMD. Sure back in the day, an AMD K7-Thunderbird was well worth it over an Pentium 4 because it performed 20% faster; but, now a days I really don't think that applies anymore with intels multi-core solutions because Intels per core performance is WAY better than AMD's. AMD is just making larger hyperthreading pipes. That's great for servers but near usless for gaming. Also, Look at the i3-2100 vs the AMD II X4 960T (same price)... the i3 scores slightly higher and only 2 cores. I think a lot of people confuse # of cores with performance but that's not entirely correct. Intel is much strong per core. And also, who need more than 2-3 cores for gaming because 99% of the games out there currently do not use more than 2 cores? Also, I loved my AMD K7, Duron and even old K5 nickel plated chip... but since multicores, INtel owns IMO. Well to be fair, I learned that the heat sink, which was the problem, is actually an AMD reference heatsink and it's the same on the PowerColor Card that looks identical> Now, I personally think PowerColor is junk but Diamond had a decent name in the past... like 8-10 years ago. Someone must have bought the name. I will now lol, But again as said above they are actually AMD reference design heatsinks from what OPs have said. PS. I am not an AMD hater, I honestly gave the 7850 a try and was looking for good performance and will pat AMD on the back for it's Overclocking though! that was aweome! On catalyst and overall chop it just fell short. But, so did the 560 TI just more on heat than anything else. How was it silly ? The original question asked by OP was whether Nvidia cards were smoother than AMD and I had an exact match comparisson that showed Nvidia was smoother. I didn't plan on reviewing them, it turned out that way from use lol. These cards were intended for personal use and both cards I picked where in the same exact price range with near similar stats baring that the 560 TI is older. I purchased the 560 TI 2GB took it back because it sounded like a jet engine at 74*C with stock clocks then paid $10.00 more for the 7850. Right now they are the best competitors at that price point unless you jump up to the 448 core. The comparison was real world based on what I planned to use and it just so happens it answered his question exactly for that comparison. I didn't think having exact facts he was looking for was silly dispite the cause... sure the cause may be drivers but the facts are still the facts... the Nvidia proved smoother in an exact comparisson. Ps My 8800GTS has absolutely NO chop/SHutter at 1680x1050 max settings no AA... is't only 30fps but it still doesn't shutter. I Bought my EVGA 8800GTS never used in the box from a co-worker for $75.00 in 2009 ...So maybe it is driver but I don't care about that... I just paid close to $300.00 for a choppy cards. If Nvida's 660 Ti acts the same way I'll be saying the same about it. PS thanks to all the posters for their input and keeping friendly!
