Rig upgrade, R9 280X question regarding PSU and bottlenecking

I'm upgrading my rig and I've been looking at two Asus Radeon R9 280X models. I'm interested in two of the following:
Asus Radeon R9 280X DirectCU II 3 GB GDDR5
Asus Radeon R9 280X DirectCU II TOP 3 GB GDDR5
My price limit is ~300€ for the GPU, and another 100€ for a new PSU if necessary. haven't really decided which one to get, but I'm hoping to get some reasonable arguments from you guys :-)

My current specs are as follows:
CPU: i5-2500k (default clocks)
PSU: Some not-very-old XFX 550W non-modular
MOBO: ASRock Z68 Pro3
GPU: PowerColor HD6950
RAM: 8GB of some Kingston RAM

My PSU has one 8-pin and one 6+2-pin PCIe cable, so I suppose that won't be a problem. I'm purchasing a new GPU within 1-2 weeks.

What I would like to know is:
1. Will my system have any compatibility problems with the GPU?
2. Will 550W be enough?
3. Will my CPU bottleneck it?

Thanks in advance.

I believe it's XFX Core Edition Pro 550W. I'm not with my PC right now so I can't confirm.

Answering ur 3 question :
1 : Yes , ur system is competible with it
2 : Yes, that is your full spec and with not much case fans
3 : I can say that your CPU wont bottlenecking your GPU for years to come ~

So my 550W PSU should handle even the TOP3 OC version?

yes ~

Edit:
If the PSU u said is urs ~
Then your PSU should no problem with R9 280X
Because it meet the requirement for R9 280X
and that is PCIe 6-pin and 8-pin connector ~

Well that's what I said in my original post, isn't it? What I was just worried about is that is 550W enough power for the new GPU+my system combo.

Thanks anyways.

actually 550W is more than enough for R9 280X ~
Just ur PSU have the power connector for it or not only ~
Mine : Cooler Master Real Power Pro 550W
Only have two 6-pin connector ~
Dont have 8-pin Pcie connector ~

Alright, sweet :) 
I might be remembering wrong, not sure if I have 6+2 and 6 or 8 and 6+2. Either way it'll work :)
