I have been searching the forums on this subject and getting some great info. However, I am looking to upgrade my card, but nothing crazy. I currently have an nVidia GeForce 8800 GTX. It has been a great card, but I am looking at all these other cards and had a little extra cash this month, so why not, right? Anyway, I run 2 monitors off my card. One is a Acer H233H and the other is a Samsung SyncMaster 226BW. I usually play games on one and use the other for surfing, watching a movie, etc. I am also looking into a new card for the HDMI upgrade aspect of it all. I have been looking at the XFX Radeon HD 5770. Am I on the right path? It has been some time since I was in the hardware "loop" and prices are always changing and new/better stuff is always comming out, haha. Anyway, thanks in advance. Appreciate the help!
The HD5770 will be a decent upgrade but not huge, something along the lines of 35% but it will also give you DX11 compatibility and use significantly less power, especially at idle.
If you can save up and snag the HD5850 it is a good idea. It would be approximately twice as powerful as your 8800GTX at stock and can overclock a huge amount(30-40%) on top of that. If you want a card that could last you 3 or so years like your old one then that is the way to go. I'd recommend this one in particular; http://www.legitreviews.com/article/1273/1/
