so should i think about getting a different motherboard ?
somone also mentioned my 550 watts wont be enough for the future ?Greg_888_v8
If you're serious about SLi, look at the list of SLi-certified PSU's rated to handle 8800GTX's and Ultra's. You more or less would need double that 550W unit to handle a loaded system featuring a pair of 8800's stably.Or if you decide to go CrossFire, you'll also need to find a PSU that can supply 8-pin PCI-E connectors in addition to 6-pin PCI-E, as the HD 2900XT uses one 6-pin and one 8-pin, and who knows what the HD 2900XTX will require for one, much less two in CF.
If you want to do CrossFire, either a motherboard based on the intel 975X chipset, (maybe) the P35 chipset (which would likely require DDR3), or the DFI RD600 motherboard would be your best choices.
If you want SLi, the ideal choice is a 680i motherboard.
It never hurts buying a larger PSU, since it only draws as much power as it needs. But having a larger PSU also means that it is also being more efficient with a (likely much smaller) actual load, and not pumping gobs of heat into your system and your room.
Even if you go CrossFire, it may not be a bad idea to pick up an SLi-certified PSU. Part of the reason is that in order to qualify for "SLi certification", nVidia says that they can't submit the same PSU to ATi for CF certification (for whatever reason). But more often than not, if it's certified to work well in SLi, it should have no problem handling an equivalent CrossFire setup, and vice versa.
As far as PSU brands are concerned, I would consider looking at models from Enermax, OCZ, Corsair, or (if you've got $$$$ to spare) PC Power & Cooling. Or if you decide to pick one up at a local store, check the weight of the PSU by itself. It's rather unscientific, but very often heavier PSU's use better quality metals and electronics inside, so a heavy PSU very often means a quality unit.Â
