Graphics card upgrade recommendations sub-$100.

[rmthompson]

Hey guys here is my current build:

AMD FX 8120
8GB Crucial DDR3 RAM
450W Power Supply
AMD Radeon HD 6450 1GB graphics card

So I am having some issues with slowdown using Lightroom and playing games. I am purchasing Sim City tomorrow so I'd like to be able to play that pretty decent.

I found some deals at Best Buy/Tigerdirect store near me, which of these would be best (I want a Brick and Mortor if I can) or do you have another recommendation? Thanks!

AMD Radeon HD 6670 1GB GDDR5 PCI Express 2.0 Graphics Card

NVIDIA GeForce GT 640 2GB DDR3 PCI Express 3.0 Graphics Card

Radeon HD 7770 Video Card HDMI (its 90 bucks right now at tigerdirect after rebate,, hoping it will be again tomorrow)

for under 100 it's tough to get a good gpu, the 6670 can do ok, it will run most games on moderate settings, if you can save up a little more and spring for a more expensive card, the 7770 ghz edition is a very solid card and will be able to handle most things you throw at it. you can get it for $120 which is a little out of your price range but it's a great bang for the buck, much better than the 6670 imo
