MOBO not hybrid, want to run nVidia GPUs... - Page 2

post #11 of 18
Thread Starter 
I think I have decided to take the longer, more expensive route, over all.
Going to get a new Mobo (hybrid), new power supply (at least 900w), and
Dual GTX 660 TIs. thumb.gif

Mobo: Asus Sabertooth 990FX r2.0 AM3+ ATX ..........................................$325.00 US
PSU: Tough Power 1350w 80Plus Silver Certified ..................................$350.00 US
GPU: DUAL EVGA 03G-P4-3663-KR nVidia GeForce GTX 660 Ti..........$340.00 US

Well regardless if you had SLI or CF, having more cards doesnt equal more VRAM. If you had two cards that has 2GB VRAM, you would still be only using 2GB of VRAM, it doesnt combine. Plus i read around that with the 192 bit memory bus the 3GB version of the 660ti is really gimped out, compared to the 256 bit memory bus on the 670 or past 500 series Fermi cards.... if you look at the 660ti, it will say 192 memory bus...

Something that has to do with the cards being built so gimped out that it doesnt even utilize the 3GB like its supposed to.... i really would suggest going with the 2GB cards. Unless you plan on going 1440p or 1600, the 660ti 2gb will do you good at 1080p. if you want more vram i suggest going with the 670 which utilizes ALL of its 2GB VRAM compared to the 660Ti which doesnt, 256 bit memory bus is supposed to be the "symmetrical"/"normal" design for NVidia, but NVidia has had history of sneaking in a "192 bit memory bus" (like in last years 550Ti).

Well I decided to go with a 2GB GTX 660 TiOC, and use one of my GTX 460s as a dedicated PhysX GPU.
Stayed with the same ASUS M5A97 r2.0 mobo, though I won't be able to run SLI without modding my OS.
I also upgraded to a bronze 80 certified 900w PSU, just to be safe.
WIth the trade in of the two HD 7770s, it only cost me another $25.00.biggrin.gif

Seems to be working well so far, and having physx is always nice. smile.gif

Didnt know you could pair a 660ti with a 460 as a dedicated physx gpu... i dont play any physX games so i wouldnt know heh. Good choice on the 660ti, and good luck!

edit:

you might need to use older drivers. read through the thread (LINK) for different fixes if you encounter problems.


Tried this, and followed the instructions, but now my system BSODs about 30 seconds after boot, and/or every time I try to change the PhysX GPU setting. So I am going back to non-sli with dedicated PhysX for now, until I decide what to do with my initial issue.

Thank you for the suggestion though.
you didn't want to do that anyways, me personally do not want a x16/x4 set-up, x8/x8 is better.
but now for PhysX I rather have it x16/x4 so install your PhysX card in the bottom PCI-e slot which I thinks runs x4 (if there is 3 slots)
I need to check but I think your board only has two, so you have no choice.

M5A97 R2.0
I checked, it has only two and will run @ 16/x4

now play you some PhysX games.. smile.gif

You can use a second or third or fourth card that is dis-similar, as long as it's not part of thew SLI configuration.
