wasnt sure if just using the single cable with a 6+2 / 6 pin connector on 1 +12V6 input was enough to power it since its my 1st card needing it or if i should be using the +12V5 inputs.. ill get pictures real quick.

I see, then your PSU has the same system as mine. All you need to do is use one cable with the 2 headers. Those headers have their own wires, I guess. But anyway, they were designed for that, you don't need two.

What CPU won't bottleneck? I planned to wait like 1-2 weeks after new fx83xx are released before I grab a new one. To see benchmarks cause I was gonna get a 8150.

Prefer staying with AMD cause I never had issues with them.

Alright ill fix it later. At work now lol. Also does it matter which side or are both pretty much the same?

I recently had this same situation on a spare rig that I built for when friends come over. I was using my 7950 in it at first and with the CPU at anything below 4GHz there is a severe bottleneck on large BF3 servers (32 players). This was with an X4 965. I since replaced the 7950 with a GTX 465 and now there is a GPU bottleneck with the CPU at 3.7GHz.

So to answer your question: Yes you will bottleneck a 7950 with an X4 955 stock speeds in BF3 online.

To answer your other question as to which CPU will not bottleneck this is severely game dependent. Since we are talking BF3 the FX-6100 and above will suffice since BF3 just loves more threads and IPC performance is not really as important as in most other games. However, if we're talking a game that is more IPC dependent than the Phenom series is actually faster unless Bulldozer is highly overclocked, in which case power consumption goes through the roof.

My advice would be this: If you can OC that 955 to 4GHz or more more keep it until piledriver releases and then see what improvements AMD has made. If it cannot OC up to 4GHz then get PD once it comes out or switch to Intel.

Witcher 2, bf3, skyrim, fable3, ffxiv(when 2.0 releases), ffxi. Basically the games I'm playing for now. Haven't looked into upcoming releases yet. I know there's nothing worthwhile coming out for consoles besides like 4 games.. so thinking same for pc the next few months

This weekend I'm gonna grab a h60 to oc for now along with new mobo/ram/SSD. So ill try to push my 955 to 4.0 until piledriver releases which is what I'm waiting on instead of buying a 8150.

Appreciate all the help from all of you guys too. Last forums all I was told or was asked is if I pirated bf3...

There's not a tremendous amount of difference between 3.7 or 3.8 Ghz Ghz and 4.0 Ghz on a Phenom II X4. I'm sure your X4 955 can make it to at least that and it would definitely help over 3.2 Ghz (and should tide you over fine).

1st time overclocking so gonna try for 3.8 - 4.0. Just gotta find a guide or get some help on here this weekend or next. Not sure if I'm gonna order the h60 or just go to CompUSA store. Depends If its same price or on sale.

That's exactly what i'm doing haha! But if the 8350 dosen't help with FPS ill be going IVY 3770K or 3570K, thats where everyone is hitting big FPS gains over AMD.

For the few games I play, when I have the time due to work I don't think switching to Intel is worth it for me.
