Video Card Upgrade?

[cetrax]

Hello I recently purchased a computer that came with a ATI Radeon HD7670 1gb card. I was thinking of upgrading. Any suggestions that will not brake the bank?

Also am I correct in assuming that the higher the model number on the card the better it is? If not how can you tell which are better?

Thanks everyone?

Well it depends on your budget, for all we know you may be able to crossfire 2 Radeon HD 7970s . It also depends on whether you have any preferences between Nvidia and AMD.
Usually a higher number means the card is better, but it's always best just to double check with its benchmarks.
