Mixed SLI

[SimonMaltby]

I'm about to buy new graphics... been sat on the fence for awhile.
Firstly i prefer Nvidia just because I like the look and feel so please dont post telling me to get a 4890

Ok i'm very undecided and have the following questions...

1. If i go for a single 295 now and wish to add another later do you think my PSU (1000W BeQuiet) will manage an i7 at 4Ghz and 2 x 295's?

2. If the answer to 1. is No, can I get a 295 and then add a 275 later and SLI them together?

3. Would 3 Tri SLIed 260's be as good as 2 x 285's

Thanks for any advice.

Should handle 2x 295's easy - fairly decent PSU.

As for them vs tri-sli'd 260's id imagine they would run one another close. Quad SLi is still not that amazing.

Might also be worth either picking up 3x 2nd hand 280's (probably the best price vs performance) or wait for the GTX275 since it's essential one half of a 295. 3 of those would also be rapid.

EDIT - As below... don't think you can mix like you can with crossfire.

u can sli only the same card. i doubt 275 + 295 will work

275 and 295 won't work I don't think. Like the 9800GX2 couldn't mix with anything. Part of why crossfire is better than sli

Tri-280s as said should be pretty good VFM.

Ok thanks for the info - I think 3 x 260's at £150 each is going to offer the best performance for the least cash. I recon it will take awhile for the 275 to drop anywhere near this level.

Yeah if you want new then 3x 260's would be best - cost the same as some 295's!

TBH I dunno what the point is going beyond 2x 260 in SLI (or a single 4870X2) even at 2048x with max quality theres nothing out I can't play at silly high fps right now.
