AMD 955BE RAM holding my cpu back?

[carpand]

Hey fellow AMD users/pc enthusiasts out there!

So, I recently put together my system (well upgraded a few parts) and right now I'm sitting with:

asus m4a78 pro mobo
amd phenom ii 955 be (oc'd to 3.4ghz, need a better cooler so I can get 3.6 ghz or even 3.8)
patriot ddr2 p6400 800mhz 2x2gb memory 4-4-4-12
EVGA Nvidia GTS 250 1gb ddr3
650w antec psu
WD 1tb sata 7200 rpm 32mb cache hdd

So, My next upgrade I had planned was a Scythe MUGEN-2 SCMG-2000 cooler for my cpu, and an Asus ATI Radeon HD 5850.

I was hoping somebody can help me out and let me know what will be bottlenecking me here? Will my RAM be too slow? My ht and nb/cpu is only 2000mhz respectively..

Right now I use my pc to play games like crysis, and for games soon to come out like Diablo 2, starcraft 2, dragons age, etc.. All high end games for the most part..

So is my RAM speed/bandwidth a problem for me? Or can I upgrade to a radeon 5850 and a beefier cooler and run my pc at 3.6 ghz (or 3.8ghz maybe) with my p6400 ram and be bottleneck free or at least minor bottlenecking..?

Thanks guys!

yeah it is a bit of a bottleneck but anything big

just OC the RAM, like to 1333 or so and u will be fine, and u have really low latency so ur pretty well off

Cool thanks for the reply. I'm probably going to shoot for 1066mhz or so oc when I get my cpu cooler.. But what about my NB/HT speeds.. they only come in at 2000mhz I feel its a tad slow?

Anyways, thanks for the reply! I'm probably going for my cooler, then my 5850 as my next upgrades!

the HT is fine but on second thought u should go to at least 1333mhz on RAM because then it would be too slow. You have good brand RAM so it should be able to handle it

The 5850 should serve u well with faster RAM

i would get DDR3 later on in like 6 months
