1440x900 when using my monitor. I plan to upgrade soon, only because the letterboxing in many games(like dark souls even with dsfix)/shows annoys me (it's 16:10.)
1080p when using my TV to play. This is usually preferred because I have a surround system and a bigger screen, but isn't always available and isn't ideal for mouse/keyboard games such as Torchlight II and such.
I did that resolution "hack" that was posted here once and upped my res quite a bit, but decided to go back to default highest because of blurry text. --- GIGABYTE GA-Z68X-UD3H-B3 | i5-2500K @ 4.5GHz| Phantek PH-TC14PE| EVGA GTX 580 | G.SKILL Sniper 8GB | OCZ Vertex 2 40GB | WD Caviar Black 1TB | HAF 912
1080p. I'm not a fan of multi monitor set ups. 1080p is perfect for me. --- Pc gamer/nintendo fan i7 3770s @ 3.1ghz, sli asus gtx 660, gskill ripjaws 16 gb ddr3, ASUS|P8B75-V R, ocz 700w psu, 1.5 tb seagate hdd
