Upgrading GPU + PSU, need some assistance

Hi, i'm looking to upgrade my GPU and i'm fairly confident that my PSU will need bumping up too.
This is primarily for gaming + recording game footage.

with that said here's my current rig:

CPU: AMD Phenom II x6 1100T 3.3ghz
MoBo: GigaByte M68MT-S2P
Memory: 2x 4GB 1333mhz
GPU:Radeon 6770 1GB DDR5
PSU: Corsair 500w
HDD: 2x Seagate 1TB 7200rpm
i don't know if this is useful but there is a small fan on the back and a medium sized fan on the top of the case. Tower casing

there are 2 GPUs i'm looking at in particular,
EVGA GTX780 3GB ACX Cooler
Sapphire R9 290 4GB

i'm open to suggestions as i doubt i would be upgrading this rig anytime soon after this GPU + PSU upgrade. Ideally i'd like them to last me a few years.

when it comes to the PSU i pretty much have no idea what i'm looking for besides a 750watt PSU pretty much. (i have no idea how to work out the Volt+Amp requirements or how it works even)
So any help in the PSU front would be much appreciated also.

That's about it i think, i've heard to 290 runs hot would that be a problem for longevity? would the 780 be a better choice?

and which/what PSU would you recommend?

Resolution: 1920x1080
hopefully play things like BF4 - Ghosts - Dark souls 2 - Skyrim on ultra + ENB that kind of thing
Thanks very much for your help, it's much appreciated.

  1. well, with the right cooler, 290 can perform great

    see this benchmark
    it is comparable to the highest clock GTX 780 from Gigabyte GHZ edition
  2. here is a reference page for recommended system PSU wattage based on the type and amount of GPUs installed:

    If you are overclocking, I suggest adding 50-100W on to their recommendation. Get a quality PSU from a top tier company such as Seasonic, XFX, Corsair (EXCEPT their CX series) or Antec.

    You might want to consider the new Asus GTX 760 x 2 (dual 760's on same card). There is a write-up about it here:,3730.html

    gives you an idea of how it stacks up against some other GPUs.
  3. nice thanks for the quick reply, i'll check those links out now.
  4. ok i've checked those links they helped quite alot thanks.

    it seems i'm looking at a 750watt PSU afterall then, you mentioned the 290 with the right cooler. Would that need to be manual added to the GPU itself or?

    ok, so i did some rummaging around the net and came across this:
    Sapphire R9 290 Tri X
    I assume that is what you mean by an alternate cooler?

    On the PSU front, i did find this:
    XFX 750W
    Am i right in assuming that those 2 would work fine together without exploding in my face? lol

    excelent choice,
    i was about to suggest that XFX 750W

    but let clear this GPU thing first
    yes, i meant the alternate cooler from sapphire tri-X is the best. tom's reviewed it recently,3728.html
  6. brilliant :bounce:
    thanks for all the help, time to get my shiny new card and psu.
