Upgrading GPU card, will my PC cope? wait for price drop?

[smeg4brainsuk]

Hi all after getting a bit extra Xmas cash i thought i would splash out a bit more than i was originally going to on a new card and as much as i want something along the lines of this http://www.ebuyer.com/279277-gigabyte-gtx-570-oc-windforce3x-1280mb-gddr5-dvi-hdmi-displayport-pci-e-graphics-gv-n570oc-13i-v2-0 to bltiz through Skyrim and The Witcher 2 i am slightly worried it will be either be
1) too much for my system to cope with or
2) over the top? perhaps something like a GTX560/560TI would suffice for my gaming needs?

Current System Spec:
OS - Windows Home Premium 7 64bit
Processor - AMD Phenom II X4 940 Black Edition
Motherboard - Asus Crosshair II Formula
GPU - Zotac Geforce 260 GTX
PSU - High Power Plus 750W
RAM - 7GB (3x2GB + 1x1GB)

Currently playing at a resolution of 1680x1050 on 22"

In addition is it worth waiting for a few weeks? with the announcement of the next gen Radeons will the price of previous cards drop soon or stay the same?

Cheers all

(though i list Nvidia cards i'm open to Radeon as i dont really mind so long as it gets the job done)

I don't know the AMD processors that well, but if you are just playing games at 1680 x 1050, even a non Ti GTX560 will handle Skyrim and The Witcher 2 at that resolutions. IMO the GTX 570 is overkill. Especially at that resolution. I suggest a GTX 560 (non Ti) if you are going to stay on that 1680 x 1050 or GTX 560Ti if at 1920 x 1080. The GTX 560TI is a brilliant overclocker too by the way.

560ti or radeon 6950, take your pick.

Ok will see about a 560TI as i would like to pump the resolution up to 1920 x 1080 at some point, is it best to get a standard one or a 448 core?
