just upgraded to Nvidia gtx 770 which is a huge increased from the radeon 6000 series i had before and i got little to no performance increase.

i am thinking it can be 1 of 2 issues

1. i plugged the card into a PCI E 2.0 slot because that is all that i have avaliable. i read some forums and it said that the difference between 2.0-3.0 is little to none currently however i am not sure how accurate that is.

2. I only have 8gbs of ram on my PC At the Moment. i was told this could be bottle necking my pc, and bumping up to 16gbs would solve the issue. Person that told me this was by no means a professional. I would liek to verify this.

I would like to know if one of these will correct my issue i am limited on funds and would like to only have to do one more upgrade.

GPU: GeForce GTX 770
CPU I5-2500k @ 3.30ghz
Memory: 8.00 GB Ram
windows 7

Neither of those reasons would affect this, you should have had a performance increase.

BUT now a few questions.
What are you using to check the difference? What game?
What resolution is your monitor?
What was your old HD6xxx series card? There are quite a few.
What power supply do you have?

the power supply has only one rail @ 55A... which the GPU needs two Rails @ 25A +/- 5A... Also it could be drivers... or your CPU and RAM... then again your playing WoW... you should benchmark it with a benchmark tool... or try a higher end Game like BF4 or Crysis 3... or something that really needs a beefier card... Also with WoW you could have it FPS capped... which you wont ever see it go over 60FPS or 120FPS depending on your settings...

is it possible it could just be something to do with some wow setting playing planet side 2 right now on ultra everything. at about 55-60 fps with no drops in battles but in wow i drop to about 20 and sit at about 40 which is about the same as my old card

Just to clarify, it's true that there is little performance difference between PCIe 2 and 3, however this is only because current cards are not using the full capacity of PCIe 3, rather than the PCIe types having little performance difference. So, it's worth thinking of upgrading to a board with PCIe 3 sometime in the next year or so.

The RAM definitely has nothing to do with the performance issue, no need to worry there.

In regards to things that might be reducing your performance, I can't think of anything apart from asking how you're measuring performance. Are you measuring it just how visually pleasing/smooth WoW is, or are you actually comparing framerates etc?

Hey, download GPU-Z, then something like http://unigine.com/products/heaven/ run in for a while with high settings, and then print screen, GPU-Z both general and sensors tabs, put it here.

Nor 8GB, nor PCI-E 2.0 would cause this, as 2 vs 3 on today's top GPUs gives none to several percent increase.

1. There is 0 difference between pcie 2 and pcie 3 for current cards unless you plan on perhaps 3 way or 4 way sli perhaps. I have gtx titan and moved it between my old i7 920 and current i7-4770k with no change.

2. Is it a single stick of ram? If so then that could bottleneck a bit as you'd ideally want 2x4 gb or 2x8gb ram for your system to run in dual channel mode.

Also check your system for temps and let us know please.

Hey,

1. i think You have not the latest Nvidia drivers, because then You would have then You would have have PerfCap reason bar in GPU-Z, update drivers!

2. Make print screen when under load, then it gives You idea of what is wrong if something is capping performance.
3. OC Yours 2500K, You payed for that K :) Mine runs at 4GHz with no voltage rise, but with custom cooler.
4. My score to compare at basic preset to make it faster: score is 2630, single GTX660

Your benchmark is at higher settings, so can't be compared. It is strange You do not have that graphs. Post Gpu-z graphs when under load, maybe someone will notice something.

im starting to think it could be the drivers.... i downloaded an older driver and was able to squeeze out another 7 average fps on the heaven benchmark but its still not really what i expected out of a card of this price. is there a cooler anyone recommends for over clocking my cpu?

I use Cooler Master Hyper 412 PS, overclock to 4GHz without any volt change, temps are stable. Max 68C tested wit OCCT for 5 min.

Then run gpu-z and Heaven on highest possible setting, tell us what You see.
