buy the card to replace 2 gtx 460 's in SLI . mainly for the increase VRAM . my 460 's be the dumb down model that only have 768mb of VRAM . which really be not enough to game at 1080p on a 1920x1080 resolution . I notice performance hit in a lot of high end game graphic wise like Crysis , Metro 2033 and even skyrim with mod install . stutter be common in large open environment and it be a pain in the ass to deal with . the 448 core fix all of these problem . no more stuttering in large open environment and I can max graphical setting without any hitch . to my surprise the 448 core be actually faster stock then my 460 's be overclock . maybe it be just my system , but most review show slus 460 's beat a single 448 core\/570 and just a hair below a gtx 580 in term of performance . overclock can fix that too since the 448 core be a great overclocker . my motherboard be a huge bottleneck for my entire system be a old am2 board but even then I have be able to push this 448 core to 880mhz stable @ 1.075 v so far . this be usually achievable with lower voltage for most people . so I 'll probably be lucky to hit 900mhz at 1.1 v. but even then the performance increase from 80mhz be noticable . the card run cool with a tweaked fan profile I have set in MSI Afterburner . it idle at around 30c and load around 68-70c while gaming . for the price I get this card at it be definitely worth it consider I 'll probably be able to turn around and sell my 460 's for a equal cost . mean this card practically cost I nothing . if you can get a 448 core for $ 220 or less then jump on it . people argue that the gtx 480 be a better deal but the card be on a older fab that run way hotter . that be the main issue I have with the gtx 480 be the amount of heat it put out and that it consume more power . another nice thing about this version of the 448 be how small the card actually be . this one be only 9 inch long . a few other like the Classified or Ultra model be 10.5 in so that may be something to consider if it be a tight space in you case . a few thing to remember if you be think about buy this card be that this will not sli with anything BUT another 448 core . a regular 560 or 560 ti will not do . so if you plan on go SLI in the future remember also that this card be a limited edition so it be probably go to stop sell soon and become hard to find . so get 2 right off the bat . another thing , if you use benchmark like Furmark or OCCT the 500 series Nvidia card have a build in power protection that automatically downclock the card to keep it within power draw specification . I find this out after run occt and think my overclock be stable . boy be I wrong and disappointed . you will have to stress stability the old fashion way of hardcore gaming and look for artifacts\/waiting for the game to crash and you driver to reload , lol .
