Upgrade path - Good? Bad? I'm open to suggestions

[Bromhead]

Ok so I've recently got back into PC gaming and I've been upgrading various parts of my existing rig and here's what I'm currently playing with.

27" 1080p monitor
6x Phenom II 1055T
GA-880GM-UD2H Motherboard
16GB Ram Corsair Vengeance
2TB 7200 RPM Seagate HDD
7950 Radeon 3GB
Coolermaster GX 650W

Next on my list is processor and motherboard. Can I upgrade these two parts and remain compatible with everything else in my system?

Total upgrade cost £285, but I feel it would unlock the true potential of the new 7950 I just put in as a the Phenom is running slow these days.

Good choice and will these be compatible? I'm open to alternative ideas or open to the option of maybe waiting for Haswell, but not sure it's worth the wait. There's always something better coming out

This is the RAM I have in the machine zak

Do you think it will be a decent upgrade? Will I see much difference? I've not used intel before so this is new to me in terms of performance gains. Before my Phenom I used an old dual core athlon

Do you think that the current 7950 I just fitted into the machine will be bottlenecked by the Phenom at all though? My thinking for upgrading the CPU, is the bump in processor speed but also the bump in graphics power that i would obtain
