So for those looking for a good graphics card on a budget, or someone with an older computer, I wanted to recommend the graphics card that I just purchased. The1GB AMD 6670. It's the ONLY GDDR5 low profile graphics card there is currently. I got it for $85 from Amazon($95- $10 rebate during March).
So now let me tell you about my system.
I was given a Dell Optiplex 360 from my father-in-law(free is free), and was immediately looking at how I could upgrade it to play TOR with minimal cost. It has a dual core pentium @ 2.6 ghz, slower but doable. It had 2 GB of DDR2 800 RAM, and I've since upped it to 4 GB of DDR2 800, which is all my motherboard will handle. I upgraded to Win 7 from Vista. It also only has a 255w power supply.
I originally ordered an AMD 6850, but when it arrived I realized it wouldn't fit in my computer because of how the motherboard was installed(stupid dell). And I would have had to upgrade my power supply.
Well I am happy to report that I am able to play TOR with all the settings on high and AA and Shadows on and I had NO lag in warzones!
And did I mention TOR is on a USB external drive?
just more proof TOR works on the low end machines, with a decent graphics card!
