Will i be able to keep up with next gen console?

The next gen consoles are going to be using tech that is considered very outdated by today's standards, so you don't need to worry.

yes but wont they be specifically built around? look at current consoles, they do very well vs alot of pcs, and the next gens will be 6 times better than the current ones.

Quoted from- http://xbox.about.com/od/xbox2/a/xbox360specs.htm

"Custom ATI Graphics Processor

500MHz processor
10 MB of embedded DRAM
48-way parallel floating-point dynamically scheduled shader pipelines
Unified shader architecture"

That is the current Xbox 360 GPU. Do not be too worried about consoles beating pc's for gaming performance  

EDIT: went on wiki and... ".....therefore very similar to an ATI Radeon X1800 series of PC graphics cards as far as features and performance are concerned...."

http://en.wikipedia.org/wiki/Xenos_(graphics_chip)

yes, but looking at those specs and then seeing what the xbox can do really do make me worry. those specs would hardly pass as a pc in 2001, and yet the graphics the consoles can produce.

You have to remember that the xbox is dedicated to gaming whereas the computer is not. Gaming computers will always have the upper hand and imo, tv's will soon have integrated gaming in them. We already have smart tv's etc. so why not gaming tv's?

That 660 will easily handle anything coming up in the next years.

Just because BF3 is a very demanding game, take a look at the minimum requirements. They happen to be hardware 5+ years old. What does that tell you?
