Suggestions on updating gaming pc

[twistoff]

As of right now my PC looks like this:
E8400, 790i, EVGA GTX 260, 4 gb OCZ 1600 DDR3, velociraptor 300gb + WD500gb drive (storage), powered by corsair tx750w, enclosed by antec 902 case. I have a single monitor (samsung xl2370, running at 1920*1080).

I'm looking to upgrade, and after doing some research this is what I came up with:
MSI P67A-GD65, 2500k, cm hyper 212, GTX570 (http://www.newegg.com/Product/Product.aspx?Item=N82E16814130621) and 8 gb of G.SKILL Ripjaws X http://www.newegg.com/Product/Product.aspx?Item=N82E16820231445.

SSD is still more then I would like to spend on a drive, and I don't really plan on going to RAID0 (since this PC is primarily used for gaming).

Any suggestions are greatly appreciated...

What of this: http://www.newegg.com/Product/Product.aspx?Item=N82E16814125356&cm_re=hd6950-_-14-125-356-_-Product (Gigabyte Radeon HD6950-2GB)

It can be "legally" unlocked to an HD6970 (direct competitor to GTX570 and has an extra 1024MB or so of vRAM, more than $50 cheaper too.)

I've never actually owned an AMD/ATI card, primarily due to issues with the drivers... Will this "unlock" void the warranty of the card?

No, that's what I mean by ""legally"" because AMD put it there and you can flash it back if you need to RMA for any reason or sell it. Only the 2GB versions can be unlocked though and as I said, it's $85 cheaper than the cheapest GTX570.

The drivers I've heard are improving and if you don't have CrossFireX then you shouldn't get any significant issues.
