hello guys, i'm building a new rig and i decided to go with an i5 3350p and an asrock b75 mobo with 8gb of RAM. now, is a gtx 650ti boost a good choice for 1366x768 resolution for gaming? or should I go for an HD 7850
well, the best GPU for 768p without overkilling is a GTX 650ti boost actually but going to a faster card is always better, so I would suggest that you go for an HD 7850 BUT what is your PSU first? you didnt mention it.
you've got yourself a good choice of PSU. of course it is very worthwhile to go with an HD 7850, it is an entry level for 1080p, take a look at this benchmarks, you'll get far better FPS than this because it is in 1080p while you're gaming only in 768P:
i would recommend you get this one, the sapphire hd 7850 has a 1gb version. 1gb VRAM is enough for your current resolution but 2gb is better just in case you want some future proofing and if you want to switch to 1080p
