Underwhelming performance on a GTX 770?

Hey everyone.

I started building a desktop last year and finally got the final piece which was the GPU. The original plan was to get a 760, but when I looked recently after getting the money for it the 770 looked more appealing and I could afford it so I went for it.

So my current specs are:

Motherboard: Gigabyte Z77X-D3H
CPU: i5-3570K
GPU: ASUS GTX 770 (the factory OC'ed one) 2GB
RAM: Vengeance 8GB 1600Mhz
SSD: OCZ Vertez 3 120GB
HDD: 500GB 5400rpm from Samsung. It was my old laptop's HDD that I put on a 3.5" adapter and connected to the desktop.
PSU: CoolerMaster 550W 80+ Bronze
Monitor: 1920x1080

So, other than this I have a Razer Naga Hex and a cheapo 10$ keyboard from microsoft connected. I also have a webcam and ocasionally a PS3 controller.

Ever since I installed I got the GTX 770 the startup has been much slower which I found very weird. What happens is that it gets stuck on the motherboard splashscreen for over a minute before continuing normally and booting. Windows recognizes the graphics card just fine and the games are running from it and much faster than from the HD 3000 on the CPU. However they are still not running as fast as they should. If I max out skyrim, according to Tom's hardware tests I should be at the very least 60FPS at all times, however it seems to cap at 60FPS and it actually goes down to 40FPS on a 1920x1080 monitor. Borderlands 2 while not being the best game to test a GPU has times where it dips under 30FPS. I run Nvidia's Geforce Experience thing to get my settings for the games and I notice that on every single game, following those settings gets me frame drops under 30FPS in some cases. Battlefield 3 and Black Ops 2 for example drop FPS as well.

This along with the motherboard splashscreen bug I mentioned before makes me thing that there's something wrong somewhere with my computer. I was guessing that it could be the PSU being too weak for this setup in the middle of a gaming session, but why would that mess with the boot on the motherboard? Can it be two seperate issues?

I'd appreciate any help to troubleshoot this :). Thanks!

At the beggining I still had the Intel drivers running for the integrated graphics, but I've removed those with Driver Fusion + control panel and it didn't seem to do anything. For antivirus I'm using Windows Defender that comes with Windows 8.

I have the normal drivers (320.49), but tried the beta ones at one point. When that made no difference I uninstalled them with control panel + driver fusion and got the 320.49 loaded again. I'll check the motherboard's bios though as that never crossed my mind!

I updated the BIOS and I no longer have the problem with the boot, however that has done nothing to fix my low FPS. Can the low FPS be blamed on the 550W PSU? Or is there something else I can do?

PSU is just an year old. I might be able to try it with a friend's one. If this doesn't fix it should I just send the card back and get a new one?

Are your games installed on the SSD or the HDD? That HDD will bottleneck everything you do, without question.
Also, are you using 2x 4GB RAM or 1x 8GB? To benefit from dual channel memory you need 2 sticks.

2x 4GB for the RAM. Most of my games are indeed on the HDD. I'll try copying Skyrim over to the SSD and see if it helps. I only keep my most played games on the SSD and those perform as expected. I get around 400FPS in LoL which is the same as my friend with the same specs as me. And GW2 dances around 40-70 with everything on max except for super sampling. I'll try to copy it to the SSD and let you know. Thanks.
