Best mobo for future crossfire of 5770

i would like to build a system with i5 in it and use the 5770 i bought previously and be able to crossfire it in the future. the available mobo in our local shop (pc express) are

MSI P55-GD65 costs 9300 pesos
MSI P55-GD80 costs 12000 pesos

ASUS P7P55D DELUXE costs 13200
ASUS P7P55D 2133 costs 9000
ASUS P7P55 LE 2000 costs 8050

my first choice was the MSI p55-cd53(7100 pesos) but lately, i want my mobo to support corssfire so that i dont have to upgrade much of my parts when my PC's performance is getting slow.

and will silverstone ST50F 500w psu support 2 5770? because
a 600w PSU costs twice as much as the 500w one.. just rying to get the most out of my money. thanks!

  1. I understand when you buy something expensive, you try to make sure you are making the right choice and that you are getting the worth of your money, I understand this notion. We all are afraid of making mistakes which is why I think it is best to just sit and wait till somebody else gets such an expensive thing for you on your birthday or Christmas, then you don't have any of these things to worry about. :P
  2. no one is giving me such expensive stuff tol. i have to buy them
  3. Add this to your list.
    GIGABYTE GA-P55-UD6 (this is a very nice board)

    No idea about Pesos. So cant say about the price!
  4. P55GD65 has 2 pci express 2.0 @x16.. will taqht be good enough?
  5. 2 pci express 2.0 @x16 means CF/SLI. If you want to go for SLI/CF then it should be into your consideration.
  6. so thats the one right?
  7. Crossfiring two HD5770 would require a decent PSU. I think TX650W is something you should get. About the mobo's, you check out some reviews and get a rough idea of how good it is.
  8. it is an ok board with OC genie (very tempting 1 button OC)

    with the PSUim palnning on buying the ST60F
  9. That is a good PSU. You can go for that. HD5770 would require approx 400W in crossfire on full load. That would give you ample room to OC and other components.
  10. Gigabyte products are hit or miss. After getting 3 new motherboards from them dying on me in less than 16 months, I can honestly tell you I will never buy anything from them anymore.

    GA-965P-DS3... worst motherboard ever designed... dying at stock settings.

    For 2 5770, you should go with AMD and a Phenom II X4 955 and a Asus M4A78T-E. A i5 will not bring that much of a gain in performance. Also, it's a way cheaper alternative.

    WTH? Are you aware that a 5970 run on a single 16X slot? That mean 2 GPU sharing a 16X slot or, if you prefer, running at 8X.

    Double 16X is a luxury that only benefit people buying more than 800$ of graphic cards and going quad GPU (2X295GTX or 2X5970).

    For 2 5770, running at speed of 2 4870, you can use double 8X without any loss of performance.

    I concur... MSI new P55 models are really looking good. Still, OC genie doesn't match a real overclocking tweaking. Still, it's a nice feature for people not really aware of how to do it.

    Anyway, my suggestion of going with AMD still hold. For only 2 5770, you will not really see the benefit over a cheaper AMD solution.

    Phenom II X4 955
    Asus M4A78T-E (2 PCIe slots at single 16X or double 8X)
    two 5770
    Some cheap OCZ Platinum DDR3 1600
    Corsair 550VX or OCZ-Z series 500W

    And you are good to go with a system that cost way less.

    Also, you should invest way more on a good power supply. 500W should do, but a good quality power supply with a good efficiency will really make the difference and preventing you some trouble if an accident occurs. The power supply is really an important component that need to be purchased with care.

    If money is really a matter, you need to go AMD.
