Please note I am NOT hardware savvy. I could be considered a hard core gamer and just got BattleField 3 and Anno 2070. Both games will run however BattleField 3 lags. Time to replace the graphics card. What do you recommend that is less then $100. I was looking at this

Here is some other info:

Operating System
MS Windows 7 Home Premium 64-bit SP1
CPU
AMD Phenom II X6 1035T
Thuban 45nm Technology
RAM
6.00 GB Dual-Channel DDR3 @ 666MHz (9-9-9-24)
Motherboard
Gateway DX4320 (CPU 1)


The research I was doing told me that i would need a "450 Watt or greater power supply with one 75W 6-pin PCI Express® power connectors recommended" and I said what the heck is that.
Please Help!

well im getting a new pc and i stumble apon the hd6870 and has loads of good reviews and people saying its amazaing for the price wich is round about £130-£170 and can run game like battlefield 3 good settings with the right cpu which you do

Your Power supply what brand and what size is it? A good PSU will run you about 50 to 60 dollars. Then the card you are looking at will help do the trick not sure if you can play on High though.

stick to AMD/ATI because they make better low end cards than Nvidia. You could cross fire but again the power supply need to know

That power supply is no good here are some that are really good
