Hi! I have a rosewill Ranger m, 8gb ram, cx430, ga78lmtusb3,2tb seagate green, fx4300 w/ stock cooler and don't yet have a gpu. I am running of the 760 g for dual monitors so you must know how bad it feels to not be able to run games at all. Gtx550ti forever died after a few years and now wants new gpu. My case has 305mm gpu support, and the sapphire 6850 is 292ish cm. will it fit okay and will temps be okay? I have a 120mm intake at 7v and rear 80mm exhaust at 7v, too. Will hd 7770 be a better choice. Play skyrim, bf3/4, cod, gta 4, half life 2, lfd2, etc... At 1680x1050 and later on will upgrade from my dual 1050p 22" Monitors to one 23 or 24 inch 1080p monitor. Fine with medium settings at 40+ fps.
