You can't link to the shopping cart. Either link each part (or combo) individually (preferred) or create a public wishlist.
Don't both upgrading yet. Sandy Bridge is due out in a couple of weeks (Jan. 9 is the last I've heard), and that will bring huge changes to Intel's lineup. I've read (on anandtech's preview) that we're looking at a 20-30% increase in performance for roughly the same prices.
I should also point out that 8 GB of RAM is practically pointless. Yes, it's cheap right now, but you don't need it. Games don't benefit from more than 4 GB, so spending extra isn't going to get you anything. Instead, spend only $40 on Corsair's XMS3 1333 mhz CAS Latency 9 or $70 on G.Skill Ripjaws 1600 mhz CAS Latency 7. The G.Skill option would be better if you want to do a lot of overclocking.
Another potential option is to go to AMD's side of the house. The X4 955 (and accompanying board, like the ASRock 870 Extreme3) will cost you around $150 less, which means you could immediately get that shiny second 5770 now.
No matter what happens with Sandy Brigde, you lose nothing from waiting. There are essentially three potential outcomes. 1.) Sandy Bridge enters the market at current prices (i5 for $200), and current CPUs get a huge price cut. 2.) Sandy Bridge enters the market at slightly higher prices and the current CPUs get a slight price cut. 3.) Sandy Bridge enters at new prices levels (like the i5 for $300) and the current CPUs aren't affected.
Under situation #1 and #2, you get either more performance for roughly similar prices or the same performance for less. Under #3, nothing changes, and all you've lost is some time waiting. I'd say that the first two situations are a lot more likely.
