crossfire or new graphics card?

[ICDP]

That case will take any card on the market, it's a good case.

Unfortunately with PC hardware, especially GPUs a year is a long time. The 5750 even a year ago was nowhere near top of the line. Using UK prices it would cost £80 to purchase an extre 5750 from a high street store. For me that would be half the price towards a good higher end GPU. You would also have the benefit of not having to mess with Crossfire. For example I have 2X HD6970 cards and when Crossfire works they are amazing, but since I play mostly sims the Crossfire ability is rarely utilised. If I could get a single GPU that was 40% faster than one single HD6970 and had eyefinity capability I would purchase it in an instant.

Good luck with whatever card you decide to purchase.
