SLI GTX275

[Cairnsey]

Thinking about SLI'ing my GTX275 for BF3 - Power Draw Question:

Would my PSU cut it? It's this one here:

I was thinking not, but at £40-50 for GTX275 off the MM I might go for it. Failing that I should sell it and put the money towards a <blank>?

Cheers Guys!

EDIT - Rest of my Spec might help

Zalman ZM600HP PSU
MSI Neo2-FR P35 Mobo (Yes I know its not SLI Supported but was thinking of trying the patch)
e6300 @ 3.33Ghz
4GB DDR2 @ 950mhz
GTX275 896Mb

Any ideas guys? I'm still scratching my head here......

its a minimum of 550w for a single gtx275, so i would reccomened at least 750w psu.

So instead of shelling out £70 for the PSU and £50 for another card (£120) I should keep my PSU and sell my GTX275 and buy a GTX460/GTX560Ti maybe? or what do you suggest?

I would definitley agree with that. 600W is enough for pretty much any single-GPU single card, and you're not at risk from the whole micro stuttering issue that's sweeping the SLI/CF crowd.

That said I don't actually know how 2x275s rank vs the card you've suggested... But if the benchmarks are about the same, then deffo single card option

I had 2 280's running fine on a seasonic 600w, so I would say 550 pushing but prob ok - 600 + your laughing (if its a quality PSU)

Think about the future though, a 750w corsair with the mega warranty could cover you for the next 5 years?

RE 560, a nice price on TWO for the palit, get one, then maybe add a second as they scale really really well in SLI.

 

[Cairnsey]

It's not a Ti though, it only has 336 'stream processors' what are they like compared to the Ti's?

 

[Mr. May]

sli 275's are very powerfull to be fair as thats what i had befor a 470 and they where much faster but no dx10

 

[Cairnsey]

No DX10? You mean DX11?

 

[Cairnsey]

Going with a 560Ti from the MM...

Good move imo, spending money on DX10 or older cards for BF3 doesn't really make any sense.

 

[CaptainUnlikely]

Good choice. GTX 460 is only slightly faster than a 275, 560 is only slightly faster than a 460. 560Ti is roughly equal to a 470 which is a decent upgrade.

I thought GTX460's were DX11 cards?! Anyway I'm trying to get a GTX570 now...if my offer is accepted

Was referring to the original idea of SLIing 200 series cards.

As an aside I went from heavily overclocked GTX260 SLI setup to a single GTX470 at first and while the 200 series SLI setup was slightly faster on paper I found the 470 smoother due to more consistant framerates (not microstutter).

 

[Cairnsey]

Ah I see, yeah I'm gonna stay away from the SLI route for now for sure...
