Hey all I'm new here but thought it would be a good place to get a few questions answered.

Recently I have upgraded from dual GTX 460's (sli) to dual MSI GTX 660 ti PE's (sli). Long time needed upgraded I know. I am running a 3 monitor setup at 5760 x 1080 and, well, the performance seems to be around the same. Not sure if it's a problem others are having but I was expecting at least a significant increase in performance going to the 660's from the 460's. Anyone know of anything I can try?

Side note* I can't OC these cards even slightly without having games crash. I've read that these cards can be OC'd though so I'm not sure what's going on there either.

Some system specs:

MSI 990XA-GD55 AM3+ AMD 990X SATA 6Gb/s USB 3.0 ATX AMD Motherboard

AMD FX-6100 Zambezi 3.3GHz Socket AM3+ 95W Six-Core Desktop Processor @ ~4.0 Ghz

16 Gb G.SKILL Ripjaws Series 240-Pin DDR3 SDRAM DDR3 1600

2x MSI GTX 660 ti power editions

Corsair GS700 700W PSU

Thanks in advance.

Your cpu might be bottlenecking the gpus. Other than that, maybe you are just playing more intense games that require more power, so you end up getting similar performance. Were you running the triple monitors with the 460s?

Yes, I was running a 3 monitor setup with the 460's. Had to turn a lot of the settings down (obviously) but they did run. Played all the COD's, Farcry 3, WoW and even the new Tomb raider with the 460's at 5760 x 1080.

In that case, I think the problem is your cpu. If you choose to upgrade, I would get the fx 8350. Best bang for your buck for cpus right now, and you wouldn't have to get a new mobo.
 




It may be that you received the first revision of the GTX660ti PE's. MSI allowed some heavy overvolting on them, this cause some to be great clocker, some to fail outright and others just being stable at stock.

This was revised on later after Nvidia went all legal on MSI.

Anyway as to your problem with SLI, OC your CPU considerably and see if that improves the issue. Bulldozer is a known bottleneck on multi-GPU setups.

I had read about that but am unsure of whether or not mine fall into that category, thanks for the info though. As for the CPU I will try OC'ing it some more and see if that helps. Thanks again.

Quick question as I have never tried it...If I were to upgrade to the specified CPU am I able to just swap it with the old one or is there anything I need to do?

Yep, they have the same socket, so you would just take out the old one and drop it in.

So i picked up the processor (8350) found out after putting it in that I needed to flash my bios to support it. After finally getting the bios flashed and the new processor in the computer takes several minutes to boot up and crashes at the windows start screen. BSOD comes up but it's too fast to read...any trouble shooting ideas?

It won't even boot up half the time. I've been trying but it's hit or miss if it decides to boot up fully.
