Hi I am wondering if it is worth buying a HD 7850 1GB instead of a 650 TI. I mostly like to play Skyrim, Black Ops II, and Borderlands, and would like to be able to play on high or ultra settings. Is the 7850 1GB substantially better? If you can, I would like a non-super-technical answer as I am still learning about computers. Thanks.
Here are my specs:
Intel i7 3770k 3.9 GHZ
16 GB DDR3 1333 MHZ RAM
900 w Power supply
1440X900 monitor (I think it is 1080p not sure though)
Your resolution isn't high, and the games you listed are not that intensive. You'll be fine with a 650 Ti. The 650 Ti is designed to handle games at 1680x1050 or under, which fits your scenario. 7850 is definitely better than 650 Ti by a significant margin, but it's overkill.
