750w for GTX570 Sli

[ARJY]

Would i be able to run two gtx 570s with a 750w power supply, a coolermaster GX. Along with an overclocked 2500k and a case with low RPM fans. Or will i definately have to get a bigger power supply, in which case i could get a 850w XFX. Thank you in advance

The 570s wiill be at completely stock clocks i dont plan on OCing them.

I wouldn't recommend it. Corsair Tx-750 £77 is a bargain. Why 570s and not 6950s though?

[ARJY]

i looked for so many reviews this may be the best so far
thanks a lot, i guess ill go with the XFX. And i dont really know why i seem to be going towards nvidia because ive heard many goodd things about the 5X0 series, would you say the 6950 is of a similar performance at 1080p and dx11?

[planet436]

The 570 is a better GFX card but it usually carries a hefty price premium over the 6950. If you can get a stonking deal on the 570 which puts it at the same price as a 6950 then get the 570, if the premium is ~£30+ then i'd recommend the 6950 instead.

At 1080 I would definitely only get one card to start with, then only buy another if you feel performance is lacking. The only game my 6950 struggles with at 1920x1200 is Metro with tessellation turned on and TW2 with ubersampling, everything else is silky smooth.

EDIT: jonnyguru is the place to go for PSU reviews, he is well regarded and undertakes very thorough testing procedures.

I could ask my friend to bring one from america where it would cost me around £220, also i was really just seeing whether or not i could upgrade to dual gpus when necessary in the future, i want to be able to play bf3 maxed out if possible.

[planet436]

No-one really knows what BF3 will require in terms of graphics. Seeing what demos are around for the PS3 indicated that is might not be that brutal on the graphics as some people are anticipating.

But definitely hold off on the 2nd card until nearer the time. With a decent 750W PSU sli/xfire on either card will be fine. If you are really intending on getting two 570s don't skimp on the PSU, they draw more power at load then the ati cards do.

ok thanks a lot mate, also about the 6950 ive heard you can work some black magic and unlock it to a 6970

You certainly could with the vanilla versions of the 6950's when they first came out, but I'm not sure you can still do this with manufacturer altered/developed pcbs.

[ARJY]

So ones with stock clocks and coolers should work? I'd still be worried about screwing it up as its my first build.

One thing I would mention is that crossfire is normally more forgiving where as sli can be a bit picky esp if you're getting one card now an another card later.

Not sure what it's like with the new cards, though.

I'd also agree crossfire/sli isn't really much needed for a single screen it really comes into play more with a triple screen or 3d setup.

Gotta admit , it does look pretty effective seeing it on the above, its pity about the panels being in the way though .

VR goggles? not for me, I tried some years back.
Ok they are probably far better in terms of weight now (the old ones where heavy, which make long usage nasty)
The big issue, that everyone who used them seemed to agree on, was that you get really bad eye strain after long usage because your constantly focusing on an image that's only a couple of inches from your eyes.

What I'd love would be ether 1- an eyefinity setup with 3 older 1600x1200 non-wide screen monitors or 2- A Zalmon TriMon, Mmmmm non-flicker 3d
Shame I just cannot afford it

If you've not bought a PSU yet grab the XFX 650W from Scan's Today Only for only £51.59, it's better than the Coolermaster 750W and will be enough for your needs.

Never heard of eyefinity and admittedly never tried the VR googles but heard a lot of complaints about the lower end models i.e. badly fitting , weight etc

I was impressed with the Augmented reality on the 3DS but no so much the games... I had one from amazon i tired with pilot wings and just found it mostly underwhelming the AR games ( esp the arrow one ) was great though, but the Zelda game just looks like rayman to me ... a port with the odd 3d element here than there perhaps. ( even that can tedious on the eyes too )

I havent bought anything yet im going to finish my a-levels, i made a bet with my dad so the money i have will depend on my grades. I just wanted make sure, are you 100% there are hardly any performance gains from sli/cf on a single monitor, itll be running 1080x1920 and if i can save money on a power supply and motherboard i will. But i just want to be sure taht i wont try to upgrade my gpu later on and realise i need to upgrade my powersupply and motherboard as well
