Strange sluggish staggering/frame rate drop

I'll try to the best of my ability to describe my problem.

In areas where there are high particle effects or "lots of shiny" my computer almost comes to a screeching halt.

A couple of examples of this are as follows.

Skyrim when there are a lot of candles (IE enchanting stations)
Skyrim when two bright windows are next to each other and a lot of that "dust" effect is coming from them.
Tera when I look at swirling water (for some reason a lot of people casting spells has no effect)

I will go from a cool 60ish frames to almost stand still only when I look at these close. If I am at any distance at all its fine.

Also in WoW this happens in areas that have a lot of ground clutter if I have ground clutter set to ultra.

The effect doesn't seem like a normal frame drop.. it is almost rubbery sluggish or like a stagger in fact it says my frame rate is about 40 (in the wow specifically). Almost like everything slows down really slow and when i move from this area things go really fast to catch up (that is noticed the most in wow.)

The rig is rather new, although budget. I feel like its a lot more jurassic than it should be. I'll list my specs below and maybe you can see a bottleneck or another problem

CPU = AMD FX-6300 Vishera 3.5GHz 6 core
Mobo = ASUS M5A78L-M LX PLUS
Video = SAPPHIRE 100358L Radeon HD 7770
RAM = G.SKILL Sniper Series 8GB (2 x 4GB) 1866
HDD = SAMSUNG Spinpoint F3 ST250DM001 / HD253GJ 250GB
OS = Windows 7 64bit
PSU = 550 watt BFG (kind of old but hasn't been used much at all)
Display = 1080p

I'm not expecting perfection with it obviously but the phenomena doesn't seem to happen on lesser machines (although they have much lower framerates)

Temperatures during these phenomena (all approximate +/- a degree or two)

CPU - 47C
Mobo - 32c
GPU - 50c

All drivers are 100% up to date

Thank you for your time.
 
Basically, that hd7770 is a low to mid range GPU. It simply cannot handle the graphics settings you have it set to when there are many things on the screen to process. You will have to lower the settings or buy a better GPU.

When frames take a drop from 60 to 40 or so, you will experience a lag spike. Even though 40fps is still smooth, when the frame rate drop 20 frames all of a sudden, it will seem like lag for a second.

All your temps are perfectly fine. Actually pretty cool.

The speeding up sensation you are seeing is not the GPU. It will happen in online games when you internet connection lags. This is based solely on your internet connection and the WOW server. Not the GPU.
 


500w is more than enough. This card pulls MAX 250w. even a 400w PSU could run this card no problem. If the game doesn't crash when the GPU gets to 100% load, the PSU is perfectly fine.

I guess I was mistaken on what was GPU and what was CPU. I thought particle effects were cpu related.

I haven't build a new PC in a while (haven't really had the time for gaming until recently) but in these high particle areas as long as I'm staring at it its like slow motion more than frame drops and in wow its not a quick jerk or anything its like start-stop-start-stop but it shows I have 50 frames. If you are familiar with the game it only happens in Azshara with ground clutter on ultra. pardon my ignorance I just want to make sure I fix the right bottle neck. I can guarantee you all know a lot more than I do about this.(English isn't my first language either unfortunately)

I guess the GPU kind of makes sense that its my bottle neck... really wish I had sprung the extra 50 bucks to get the next best :( a friend of mine told me it could be ram or mobo but that didn't seem to make sense to me

Thank you all for the very quick responses!

Thanks for the feedback guys I'll look at making a new video card my next purchase. Quick question while I'm here. If I were to get another AMD card would it have to be the same one as the one I have to do crossfire? and is it worth doing? Thanks again!

one more update. Just as a test I tried a friends HD7870 in my machine and had the same strange sluggish phenomena in those areas. The only difference was instead of it saying 40fps with this strange rubbery stagger it was saying 80fps in these areas. I tried his ram as well with the same result. I am going to reformat today and re install everything just to make sure it isn't a software problem. (most likely isn't but we'll see) Provided that doesn't fix the problem do you have any ideas? (still going to upgrade the video card though really wish I hadn't gone cheap on that)
