Default Questions about (Tri) SLI and Pin Adapters

How well does a Tri SLI setup scale with new drivers? I'm wondering whether going from 1x GTX 275 to 2 or even 3x GTX 260's is worth it.

What is your opinion on Molex to 6 or 8 pin adapters? I currently have a Corsair TX 850W (Non-modular) power supply and it only has 4x 6/8 pin connector dudes. If I go tri SLI or something, I'll need an extra pair of 6 pins.

Would 850W even be enough to run three GTX 260's? My current rig is in that list and I'm running an MCP655 with a multitude of fans. I read somewhere (can't remember now) that someone ran two GTX 260's on a 500W PSU, but maybe that was on a lower end CPU/mobo/etc.

Thanks, HWC

No. Get a 5870 instead.

They're perfectly fine.

Some guy was selling 3 GTX 260 core 216's with waterblocks for $540. I guess it would definitely be better to grab a 5870 with a waterblock lol

I was just curious as to whether or not my current hardware would be able to support it.

Your current hardware can support it, unless you are folding going that route for say gaming is worse off then going for a 5870

So you guys are saying that a single 5870 will provide better performance than a Tri Sli 275 arrangement?...I beg to differ....a Tri Sli 275 arrangement will outperform a single 5870....especially with Full AA/AF cranked...not a doubt about that!! Provided you have a handle on some cheap Cards...go for it...the Scaling from SLi to Tri SLi is amazing on those Cards....yes your 850 PSU is perfect!!

If you cannot get a good price...even a SLi 275 would perform at around the same level as a 5870...maybe even better with full AA / AF...remember though...you will have no DX11!

Really curious ....all "Fanboyism" aside...and other than DX11....your saying Gaming on a single 5870 is better than a SLi or Tri Sli 275?.....I really doubt that...perhaps SLi would be close...but Tri Sli ...you my friend obviously haven't tried that route...

Remember...I;'m saying he finds a great deal on those 275 Cards...still better off than dumping $500 on a 5870 for shvttier performance...

Now don't get me wrong....it aint worth it if you have to pay a "premium" for those additional 275's.....then "perhaps" a 5870.....it all depends upon what your expectations are n what your willing to spend!....oh...and Res!

Tri SLI of GTX 260's will be faster than a single 5870 or GTX 480. I just came from TRI 260's and went with 2 480's as there wasn't enough performance gain going with just a 480.

It is up to you if you want performance or DX11
