Upgrade advice

[ginandmilk]

Ahoy hoy.

I'm a bit out of the loop with the latest hardware, was hoping some of you good people could advise me on some upgrades.

My current setup is getting a bit long in the tooth and I'm after something that will hopefully play the latest games on reasonably high settings (especially Battlefield 3). 500ish quid to spend.

My current system:

Phenom II X4 955
Asus M4A77TD Pro
Patriot G Series 4GB RAM
4850 512MB

I definitely want to upgrade my graphics card and I've been looking at the 6950. Is that the best card to go for with ~200 quid to spend?

I'm also seriously considering a new case since my current one is pretty cramped. I like the idea of a full size case and the Antec 1200 seems to be the stand out model for the price. Can anyone suggest a better case than the Antec 1200 for the money?

I'm a bit reluctant to shell out for a new PSU since my trusty OCZ modstream 450W is doing a sterling job but I'm worried that the cables won't be long enough to reach inside a larger case and will 450W be enough juice?
Reccomendations for a new modular PSU? And does anyone know if the cables are actually longer on newer models?

Also, is it worth getting more RAM?

Thanks in advance.

It'll definitely be air cooled I go for. Those Raven cases look pretty mean! Same money as the Antec too I see, I'll have to have a think on that.

My chip is the black edition, I hadn't even considered an overclock since my current case can get pretty toasty. I'll certainly look in to a new cooler (using the OEM one at the moment), is the Gelid model best bang for buck?

I'm using an old 19" monitor at the moment, 1280 x 1024. Its next on my list to upgrade though.. I'll fork out for that next month.
