Graphics card upgrade query, new card vs Cross-Fire


I'm looking for some advice on a graphics card upgrade as I'm a little rusty and built my PC around 5 years ago.

Essentially I'm looking to do a bit of an upgrade and don't want to spend more than £100 on a new graphics card, so I'm wondering whether it is worth buying a new card or getting hold of my old card (for about £60-70 i think) and using Cross-Fire.

My current spec:

Intel core i5 750 2.66GHz LGA 1156 8MB L3 cache

ASUS P7P55D iP55 LGA 1156 motherboard

Sapphire HD5770 1GB GDDR5 Dual DVI, HDMI display PCI-E

(Link to my card specs below, I have the long one and if you search for the model on google, it usually comes up with the short stubby model).

Technology GDDR5 SDRAM 128-bit
Features ATI Stream technology, ATI CrossFireX Technology
Graphics Processor / Vendor ATI Radeon HD 5770
Clock Speed 850 MHz
RAMDAC Clock Speed 400 MHz
Memory Clock Speed 4.8 GHz
Video Memory Installed 1 GB
Video Output
Max Resolution (external) 2560 x 1600 / 60 Hz

So to sum up:
- Is it worth trying to pick up my card and using Cross-Fire? (I think I might be able to get my card for about 60-70 second hand or old stock)
- If a new card under £100 is better than two of these, could you please recommend one
- If I do crossfire, could you please recommend a minimum PSU Wattage

Any advice would be greatly appreciated.

  1. Also my current PSU is 600W
  2. After looking around, it seems I can get my current card for quite cheap, so quite interested in that option if its going to make a noticeable performance difference

    Doubtful a new card for $136 or £100 is going to be better than two 5770's. If anything the performance would be the same. Save your money and wait. A single Radeon HD 6850 (the only thing in your price range) isn't going to cut the mustard for today's gaming. I have 2 of them in crossfire and they have a hard time keeping up.
  4. thanks all,

    Think I've found a very cheap copy of my card so think I'll cross-fire for now and save up for something juicy.
