Upgrading from HD 5770. Buy a GTX 660, 670, or wait?

[markusaurileus]

Hi, I really try not to ask these kind of questions, but I've looked around articles and posts, and still need some extra help.

I currently have the following system:
Core i7 930 2.8GHz
2x4GB 1066MHz DDR3
HD 5770 1GB

I would like to upgrade the video card between now and early January, maybe even later into late spring. I'm looking at cards from Asus, as I've had a GTX 460 by them before, and it had performed well and very quietly.

So should I get a GTX 660 2GB for $190, a GTX 670 for $260, or wait a little longer for a better deal?

I've read the 660Ti outperforms the 660, and 660Ti performs like a 670, but the 670 has higher memory bandwidth or something. But I don't know how the price/performance is for each of these cards.
Also, I don't really know how the prices will be in the future, which is why I can consider waiting because I'm in no real rush to upgrade. Just want to have a better deal this 2013-2014. Thanks.

With AMD's new cards, Nvidia GPU prices should shuffle around a bit over the next two months. If you were planning to buy in January, prices should be mostly settled by then, which should make it a good time to buy. Boxing Day deals might be worth a look too.

When you say 'settled' do you mean that the current series cards' prices are permanently dropped, or the newer cards' prices are coming in?

And I'm not familiar with boxing day… is it like black friday?

When new GPUs get introduced (AMD's 260/270/280/290), older models get discounted, discontinued and competing products (Nvidia's 6xx/7xx) get price shuffles too. Over the next couple of weeks, AMD's AIB partners will also start introducing their non-reference designs which may cause another wave of re-pricing activity.

As for Boxing Day (or Week), it is the time between Xmass and New Year's where merchants are discounting their excess unsold pre-holidays stock to get rid of excess inventory, discontinued products, etc.
