Best Mobo for twin GTX 460s ?

post #1 of 4
Thread Starter 
Hi.

I'm building a new rig and I would like to know which Mobo would work best with 2 gtx 460's.

I read that the ASUS Maximus III formula had problems with the GPUs sitting too close to each other and causing heat issues.

I also read that i should just go for a single 480 GTX instead of 2 460s.

I'm on a budget but I'm building it slowly so I have time to look for deals and such.

My build so far. ( Any input about the rig in general will be much appreciated, I'm a little new in the computer building scene) i.e bottlenecking with the i5 ?

- Case: Antec 300 or maybe an Antec 1200. I would have to destroy the blue LEDs though. biggrin.gif
- CPU : Intel i5-760 @ 2.8 Ghz: no HT but i've heard great things about it. I will OC it. ( Don't know if getting an i7 is worth it. )
- Ram: GSKILL (2x4G) DDR3 1600
- GPUS : 2x GeForce GTX 460s ( EVGA ?)
- Cooling : Cooler Master Hyper 212 Plus
- PSU : Antec TP-750 ( would like a modular PSU pref with the 1200 case but we'll see )
- HDD : SSD maybe ?


This computer will be mostly used for gaming and 2d/3d Autocad and Catia, no photoshop though.

Alright, well for your needs I would definitely recommend GTX 460s over a GTX 480. You will see much better performance with the SLI. I wouldn't worry about the motherboard too much personally, also.

As far as i7 vs i5, with the applications you listed you may be able to take advantage of hyperthreading. With hyperthreading you will see a 15-20% performance boost in those applications. You will also get 5-10% more performance out of your graphics cards if you go 1366 instead of 1156 because you can use two x16 PCI-E lanes vs. two x8 PCI-E lanes. That being said, you will definitely still see excellent performance with the i5. It is really up to you if the extra performane is worth the extra cash.

I would NOT recommend going 1156 with 1155 coming out in exactly a week. 1155 is going to have FAR better performance than 1156 and FAR more overclockability for around the same price. It just makes no sense to go 1156 at this point. At least wait for 1155 and see how much the 1156 prices drop if nothing else. biggrin.gif

Hope I was of assistance. wink.gif

If you want to go nuts with an overclock and get the best performance then the MSI Big Bang has been showing the best results.
but you are really fine with any SLI mobo.

Thanks a lot for the info. I will definitely wait after CES to make my final choices, the new intel i7 2600K is making me drool and seems to have more oc potential than the i7 950 I intended to buy.
