Is the HD 4890 overkill for my system especially considering I use 1680*1050?
Would it be better to go with an HD4870 that is OCed or better cooling?
Or is crossfire the way to go?!
I'd go 4890. At that price, if you don't mind rebates, it is an amazing value. It is going to be a touch slower in some benchmarks than the dual 4850s but then you have zero crossfire issues to deal with only having one GPU.
It is a little more than that resolution needs but extra power at that price shouldnt hurt.
Not enough to make one of the more legit reasons not to do it, as we all know gpus are getting hotter and hotter thus the term "hot running gpu's". Such as games bias or pricing although pricing is like 10 dollar diff woop de f doo.
Really at that rez 4870 1 gig should do fine. But for not too much of a big diff in price now you can get a 4890 which is a we bit better and we all like better.
1) I like a single card solution whenever possible.
2) You mostly get what you pay for in video cards. It is very competitive nvidia vs. ati. Don't sweat the minor differences, and get the best card you feel comfortable paying for.
3) Consider spending a bit to upgrade to 4gb. Here's why: http://www.corsairmemory.com/_appnotes/AN804_Gaming_Per...
