I'm currently using an Asus M2N32-SLI Deluxe, which has the nFoce 590 chipset. (AMD motherbaord)

I'm looking forward to puprchasing a pair of GTX295's to use in SLI as an upgrade to my current 8800GT, but I am wondering about compatability. I'm aware my motherbaord is aging, and have been considering buying a new one.

Will I need to upgrade my motherboard to use SLi for the GTX295, or even the 280?

GTX295 SLi would be working in your board..... I think your board don't support 1066MHz RAM..... latest boards support higher bandwidth...

Your board would support SLI of new cards but would definetly be bottlenecked by your CPU, the most you can put in that board is 6400 x2 which will bottleneck 2 GTX 295's

I've actually got ax X4 9850 in it, the board supported them with newer BIOS upgrades.

Also, I made a mistake with saying its nForce 590, it's actually only 570 upon looking at CPU-Z. I'm presuming this wont make a difference?

oh, another question - will a 600w power supply be able to support one card? (i'd hazzard a guess that SLi would require a PSU upgrade)

600 Watt PSU may be dicey at best with a 295 as you are basically SLI'ing a pair of 260s with that card so I would imagine that power consumption would be close to the same. Might be time to step up to a quality 750 watt PSU.

ANy recommendations? ;p

I've heard good things about this one from PC Power & Cooling, and simmilarly this one from Coolmaster. There any brands/models that should be avoided?

SLI with GTX 295 will require a 1000W PSU, I think. That's what they recommend already for GTX 280 SLI, and the GTX 295 will very likely consume more than a GTX 280.

You'd be disappointed with GTX 295 SLI anyway, because that's a 4-GPU setup and games are not optimized for such things. I've seen this with 9800GX2 SLI and HD 4870 X2 setups already. I'd just get a PC Power & Cooling 750W (search Newegg for "S75CF" ) and a single GTX 295.

Oops, based on that link I'd say you're in the UK. No newegg for you.

PC Power & Cooling is one of the best PSU manufacturers. Personally I think they're #1, but Corsair has its fans too. CoolerMaster PSUs on the other hand have a bad rep. Get that PC P&C or a Corsair 750W.

The PC P&C you picked is not in stock, but this one is:

Same thing, except it's red. I got the red one myself.

Here's the Corsair, almost as good and cheaper:

Allright, cheers for the help :]

Looking forward to buying the 295 tomorow, provided there are no shortages...

oh and...will a phenom X4 9850 bottleneck this card? (Slight overclock)

Upgrading to an i7, hopefully, next month anyway ;p

No, it won't bottleneck it. For example a Phenom 9850 at 2.5 Ghz got 113 fps in Quake Wars at 1920x1200, where a more expensive Q9650 overclocked to 3.6 Ghz got 140 fps. Since a typical LCD can only display 60 fps anyway at that resolution, the two CPUs give a perfectly identical experience there, i.e. 60 fps. The experiment was done with a HD 4870 X2,but it's the same thing with GTX 280.

Crazy thought: does your M2N32-SLI support a Phenom 9850? Check before you buy. I'd check for you but there's a bus strike in my city and I got to go right now or I'll lose my ride home :)

It did require a bios upgrade, but yea it supports it.
