I usually play minecraft and WoW. I bought skyrim thinking it would work on minimum graphics but it didn't. So i have decided to upgrade my psu and graphics card so i can play games like skyrim etc. It doesn't have to be with max settings or anything I just want it to run smoothly ( moderate settings would be nice). If what i'm asking for can run off of my stock 300 w psu then please tell me.
I have an acer 21.5" x213w monitor and I don't use the reccomended or native resolutions because for some reason being so zoomed out makes my eyes hurt. The resolution i use is 1280x960.
My budget is around 100$ and I will probably need a new psu so i could go a little bit higher than $100.
Read the article in my signature link. You will not be able to upgrade the video card and power supply for $100, maybe $150. The 6770 are just over the $100 mark. A 6670 is just under $100 and a 5670 is under that, but your CPU is a tad too good for that. A 6670 may actually run on your system without a power supply upgrade, maybe. To be safe though, you should upgrade it, and if you want a good cheap gaming video card, 6770 is good.
The power supply you listed looks to be OK, the brand has some good reviews.
