so here 's my story . . I recently purchase a 27 '' HP IPS monitor -lrb- zr 2740w -rrb- that have 2560x1440 native resolution -lrb- which be fantastic btw -rrb- primarily for photo editing . I previously have a 1080p monitor , but I have to zoom in too much to deal with my rather large image from my Sony 24mp slr camera . the gt 240 video card in my Dell XPS 8000 computer drive the new monitor ok , but struggle quite a bit try to run any game -lrb- crysis -rrb- at native resolution -lrb- or even 1080p -rrb- . so I decide to look for a new card that would 1 -rrb- fit inside my Dell 2 -rrb- play game at 1440p . I research online extensively , and initially choose a gtx 560 ti card . but I discover read various forum that this card would not drive 1440p very well . I then be lean towards a Radeon 7950 or 7970 , but the dimension of those card would be extremely tight in my case . so that lead I to the gtx 670 . most site recommend the 670 ftw edition from EVGA , so that be what I order . the card arrive quickly -lrb- thanks Amazon Prime -rrb- , and I install the card along with a new Corsair 800w power supply . it be a tight fit for sure , and I have to move my hard drive to a different bay to make it work . the card be at least a inch longer than the gt 240 that be in it before . besides the tight fit , installation be fairly easy , and load the driver be painless . once I get my pc run , and loaded Crysis to test it . wow . Pretty damn cool . the gt 240 give I choppy frame rate at 1080p -lrb- medium -rrb- . the gtx 670 give I super smooth gameplay at 1440p -lrb- high setting -rrb- . I can not tell you how good a game look in 1440p , but it definitely make I feel better about drop money for my new monitor . then about 15 minute into the game , my computer get white ` spot ' all over the screen and freeze . WTH ? I have to do a cold reboot . later on , I run the ` OC Scanner ' utility to run some benchmark test , and again my computer freeze . in total , my system freeze 5 time in 2 day , and I be start to get frustrated drop over $ 400 for video card that freeze my very reliable computer . I read more forum online , and discover that several people have have this issue with the 600-series card . I start regret my purchase , but keep research online for solution or ` fix ' . so far I have uninstall the Nvidia hd audio and 3d driver , enable software control on the fan in precision x utility -lrb- its not enable by default -rrb- , and set the fan curve more aggresively . I do not know if this permanently will prevent freeze up , but I do manage to play Crysis for almost 3 hour yesterday without issue , so hopefully this work long term . if it do , than this card be absolutely fantastic , and I could not ask for more graphically speak . if i continue have issue with the card , than the card be not worth the headache . I 'll give it a 5-star rating -lrb- base purely on performance -rrb- for now , and update the rating if the issue continue . Hope this help !
