Like you guys said, i dont HAVE to upgrade. if nobody will want to buy the system as a whole i will just wait and sell the parts when i upgrade next year when Haswell is released.
Its working perfectly and i have no complaints, just got bored and thought i might get something else, thats all.
tbh, you're not gonna get anywhere close to 1800 if you sell it online here or on H/OCN/etc.
If you got the itch to upgrade, you can upgrade your GPU to a kepler GTX 680 or GTX 670
anything lower than that is a sidegrade/downgrade imo.
Or go AMD 7970.
Or can always get another GTX 580 and SLI.
Like others said, SSDs have really dropped in price, no reason for you to still be on a 64gb
i recently went from a 128gb M4 to a 256gb M4.
To improve your experience in gaming, like others said maybe time to invest in a new monitor if you're still on 1080p resolution
i went from a 24" dell ultrasharp at 1920 X 1200 to a 27" dell ultrasharp at 2560 x 1440
yeah i lose out on the 16:10, but it looks so crisp and clean, and its still a good amount of space to work with
I'd prob get another 27" monitor sometime soon, or go 3 for nvidia surround.
