Honestly, which is better? Both have 512mb of vRAM. Both are around $200. I have looked through countless benchmarks and they look to be equal. Which would be the better buy? Just playing at 1440x900 and possibly 1680x1050 in the future.

I know nvidia is on top of the ball with driver support. ATI seems to be....lacking...

Also, what is the main difference between the GTX and GTX+?
