New video card

[tk471138]

I am building a new system, this time since i dont like the Nvidia cards out on the market right now i am planning on getting an ATI/Nvidia card Radeon 6850...

Now i have been using Nvidia Cards for the last few computers i have made...the problem is i dont like any of their new cards or the prices that go along with them...(i currently have an gtx450 1gb card, that i got from the warranty of a 8800gt however it is hard to gauge the effectiveness of my current GPU since the CPU is heavily bottle necking the system and GPU % usage generally stays low)

so what are the pros/cons of ATI vs Nvidia...does this game still have that blue lines horizon bug....and other in general comments you guys have...

(the only other game that i WANT to be able to play on the new build is arma2, so insite in to this would also be appreciate by me)

PS is anyone else pissed about the prices of Hard disk drives?? at this point i am leaning towards just using the one from my current pc..
