Upgrading from GTS 250

[horribad]

Hi guys.
I'm upgrading from a GTS 250 to something else.
Someone mentioned the GTX 550 and the Radeon 5670 as possible upgrades.
Is there any truth to this? I know nothing about specs so I need help!
Thanks in advance.

My cpu is a dual core 2.8Ghz. I got told about bottlenecking and I'm concerned if this will happen with mine. so the GTX 550 is a bad choice?

What if I was to get the Radeon 5770?
Would that be a good fit for my system?
I'd pick up a CPU later and yeh I'm on a tight budget.

What in your opinion would be better though? CPU or Gfx card? Ive only got 100 quid max to spend.

i have a 1000w psu. bit overkill for what i have but i reckoned it would last me a good few years

was looking at the GTX 550 Ti. is that any good?

my monitor1920x1080 but really i prefer windowed mode (to browse the web on the other screen i have) so i usually end up at 1366x768 wndowed (dont judge me!)

and yeh that 460 looks right up my street price wise, this GTS 250 nets me 40+ fps in most games on medium (i dont really mind about high) while stil retaining the dual screen functionality so if i can play Battlefield3 on that card on low-medium i honestly dont mind. will this be possible?
