I recently bought a 6770, and are looking to make an upgrade to a better card before the 30 day period is over
APPROXIMATE PURCHASE DATE: This week BUDGET RANGE: $100-150 CAD After Rebates
USAGE FROM MOST TO LEAST IMPORTANT: Gaming (Battlefield Heroes, DiRT3, Skyrim, Shogun II, some MMORPG's), Power computing, Youtube, Video calls, Multitasking (on skype with three chrome windows open while playing a game)
OTHER RELEVANT SYSTEM SPECS: Corsair Vengeance RAM (2 X 4GB), Intel i5-2500k, Asus P8Z68-V LX
PREFERRED WEBSITE(S) FOR PARTS: Preferably Tiger Direct, Maybe Newegg if the price is over $10-15 better.
COUNTRY OF ORIGIN: Canada
PARTS PREFERENCES: No Preference, Something with good tech support and a decent warranty, especially if OC'ed
OVERCLOCKING: Maybe, only if the card is factory overclocked
SLI OR CROSSFIRE: Probably not.
MONITOR RESOLUTION: Currently a 19 inch 1024x768, Will upgrade to a 20-24 inch 1920x1080 monitor soon (In about 1-2 months)
ADDITIONAL COMMENTS: Must be able to run with current PSU, must provide decent performance, and basically everything i listed above. The cheaper the better IMO, also note that i wont be running games with 8XAA or stuff like that, probably just high detail.
A 6850 would be in your budget range and would be an upgrade to the 6770 , I'm not sure if you would be able to find a 6870 for under $150 but even if it went a little over it would be a better upgrade then the 6850.
