Don't see any obvious hardware bottlenecks, but you may want to bump the ram to 8GB (it is cheap) and overclock the CPU (3.8ish GHz) and see where you stand. Stock CPU cooler? Where / what do you see as your bottleneck? Symptoms?
SSD - OCZ Agility 2 / Vertex 2, A-DATA S599, etc... Look for and SSD with a SandForce SF-1222 controller.
Well it could just be me, but I feel I could be getting more out of games like Metro and Crysis, they seem to slow down at times (Crysis more so) metro stays around 45 FPS with everything max (except PhysX)
I saw a sale on 8Gigs of RAM that should match my current set, so maybe I'll get that today.
Also I do have the stock cooler on my CPU (so it gets loud at load) but headphones always help
I guess I could look into a new CPU cooler I saw a single cycle water cooler for my socket type on newegg.
I just want to avoid stuttering/shuttering in-game while maintaining maximum detail.
The most simple way to buff your system performance:
Get a very good cooling system.
Read here : http://www.frostytech.com/ and you have a lot of different cpu coolers reviews,so you choose a cpu cooler.
It really worth to get very good cooling considering the mainboard you has 8+2 power phases for cpu power,and the PSU you have.
I saw 4.5 ghz on air on Phenom II x6 on the mainboard model you have,that takes a lot of power from the mainboard source,so it should be no problem you do also on your cpu 4ghz+.
For air cooling you need that your room temperature where you keep your system is not too high (20 celsisus degrees,that is 68 degrees F,that would be a good temperature).
If you are willing to spend more $ you can also get a Phenom X6 (after geting a very good cooling device for the cpu) and overclock it at 4+ ghz.
I was only running through the idea of what more RAM would help me with, and it wasn't much.
As for upgrading my CPU to an II x6, I choose the x4 for the specific reason of gaming performance, I don't know of any titles that use more then 4 cores to help process so unless I saw actually proof of the x6 doing better in the titles I enjoy upgrading would be out of the picture.
I do keep my room cold enough, but I also have a small room so my CPU fan is audible at any speed, thus bringing me closer to the idea of silent cooling.
Sure there are other options too since you can customize the fans you put on your cpu radiator,if you like a silent room you can get fans that are silent.
(Noctua nh d-14 have low sound level cause of those fans it has on it)
On most tower coolers you can put 120mm fans,and you can put 2 of them.
The Noctua is HUGE it will barely fit in HAF 922 (according to a long thread I read recently whose link I'm too lame to post)
Make sure your case can fit it also am not sure if you'll have to remove your MB before mounting, depends on your case (did you mention it earlier and I'm just a nimrod).
If you do end up going with the Noctua use the included paste if the cooler master get some arctic silver 5 from your local radioshack
For almost all serious air coolers you need to remove the MB from your case,to put the backplate when you install the CPU cooler.For hyper 212 plus (which is a serious cooler) you also need to take the mb out of the case.
Since you have an AM3 board you need to also remove that plastic that is around CPU socket,fixed with 4 screws.
(in which the default cooler from processor box is fixed - some are calling that plastic "retention bracket").
Cause in those holes you will put the cooler screws.
Since theese coolers have usually above 500g weight would be weird to use that mounting system that is made from plastic that is used also by standard cooler that comes in CPU box.
For example hyper 212 plus weights about 650 grams.
If you want a cooler for which you will not need to take your motherboard out,Scythe Yasya is not requesting that (http://www.newegg.com/Product/Product.aspx?Item=N82E168...).
However I find it weird to fix a 850 gr (the weight of Scythe Yasya) cooler on that plastic thing.
(Scythe Yasya use same retention system as default cooler which comes in the CPU box).
Is not sure that you will not have problems with the ram in your slots,if you choose Scythe Yasya ,because how is put the plastic retention bracket on mb the heatsink will be over your ram dimms - If you have low profille dimms (not that tall) you will be fine,otherwise not.
I never saw you link the Shuriken, but I like how it looks (seems small) and reminds me of a better stock cooler.
Something I should add is my case, and the reason I can hear my fans is my room is small I mean small, if I move my computer to anybody's house that has a room larger then 3 single beds I don't hear my fans past my headphones.
My case is a Hades NZXT
Also I should add, I'm not willing to remove my motherboard, so if that is a must I would rather wait until I upgrade another part like my PSU before pulling it out.
