1) when will you build your new system?
Next year means 2012?2) What kind of power-supply do you have?
kinda makes the difference on what you can buy3) make sure you check out your motherboard really good!
your GPU might have damaged the slot (or the other way around), increasing the chance you wreck your new GPU4) How much do you want to spend?
When i make a new system, i generally want to spend up to 200 euro's on a card, for an inbetween card like you might
want now, i would spend at max 100 euro's. Do note that Ati cards are still the best performance for your money in the lower / mid bracket, and that Ati introduces a new line every autumn. The best way to spend your money (imo) is to buy the top-end cards of the previous serie when the new one is introduced and the prices drop. I bought my HD4890 oc right after the first 2 cards of the 5xxx series hit the store. (they are currently in the 6xxx series)
For an inbetween card i would suggest the 5770, its 98 euro's.
The card Splish just recommended is a step higher in price (150), at which point you will be entering the 6xxx series of Ati (6850- 140eur).
but, best advice i could give you is the dutch website Tweakers.net, releasing a best buy for pc games every month:
