Time to Upgrade or crossfire?

hey everyone at Tom's :)

I am thinking about upgrading my Computers gfx card ( Im starting to notice low fps on dx11 games such as BF3 ) + extended desktop has constant artifacts.

I am wondering whether it would be worth upgrading my power suply and buying a second HD5870 around £200-ish
or just leaving my PSU and buying a straight out better card ( around £200 budget)?

My computer is used for gaming at 1980 x 1080, Programming (XnA games for windows phone/xbox), and some 3D redering.

My specs should be in my sig, I prefer Radeon cards as my motherboard is x8/x8 crossfire compatible, and I have always used these cards.

My questions are:

would you recomend a new card or crossfire with a PSU ugrade?
Do you think my processor is still ample for gaming ( would'nt bottlebeck any gfx upgrade I did )

Thanks for your time

More about time upgrade crossfire
  1. Processor limited for that title. Crossfire would help with the memory bottleneck but there's nothing like a good benchmark on the internet with a more modern processor to verify this build on BF3.

    Personally, if possible, an upgrade to i2500k system with a solid graphics card would be in the works.
  2. really? It is clocked at 3.9ghz? and that is well out of my budget I only have around £200 free money to spend. Im a student you see. Most I could do is upgrade maybe motherboard and processor its a bottleneck issue.
  3. what PSU do you currently have?

    as your going to have to spend a fair amount more that 200 to outperform 5870's in Crossfire.

    about the only thing that beats 5870's in CFX is a 590, 6990. a 7970 is about the same as 2x 5870's in crossfire.
  4. there would be little diff changing ur CPU to a 2500k.

    I went from a 1090T @3.96ghz to a 2700k @ 4.5ghz and i did not feel alot of real word impact. (in games anyway)
  5. I've got 500W Corsair Builder Series 500CX V2 80PLUS Power Supply

    But there is no chance that would run two of them in crossfire right? I saw a second hand HD5870 but £120 today and it got me thinking...
  6. Nice PSU but I think will struggle in CFX

    ATI Radeon™ HD5870 System Requirements

    • PCI Express® based PC is required with one X16 lane graphics slot available on the motherboard
    • 500 Watt or greater power supply with two 75W 6-pin PCI Express® power connectors recommended (600 Watt and four 6-pin connectors for ATI CrossFireX™ technology in • dual mode)

    i would look at 750w+ to be sure tho.
  7. so you would say that upgrading to a new PSU and buying a second hand HD5870 would be the way to go... and last me a couple of years? :)
