That is a good decision, and it's nice to see see a man who can use his sense in the face of people telling him to buy the most expensive re-hashed cards available now before a major architectural change is due. You would have regretted it, trust me.
Go for the version of the OCUK panel with HDCP... is it the Yakura or something? There's loads of details around on ze web. It's by far the best purchase at the moment, get it while it's still around so cheap, i'm tempted myself!

Another change i would make to that is to scrap those 2x 150GB Raptors... they are hideously loud and my case vibrated so badly I wanted to scream, god knows what 2x would be like! I swapped mine for a 320GB Samsung Spinpoint F1 and haven't looked back since, they are just as fast in 9/10 situations and about 100x quieter. Raptors really hold few benefits for the average home user, they are getting very long in the tooth. See this thread for more details and benches

Also, and this is quite important, if you are after a 1TB drive have a re-think on that Samsung. Yes, it's blindingly fast, but it's also got concerns over reliability according to many reports on ze interweb (lots of RMA's on them) and has a shorter 3 year warranty, which on a 1TB drive is not what i'd be wanting with all that precious (Gollem voice) data!. The Western Digital RE2 1TB GP drive is not only low-power and very efficient (verrry quiet too), but backed by a 5 year warranty and should be very, very reliable as a data drive. Personally i wouldnt use the Samsung F1's for anything other than a boot drive in 320GB format.

Also consider PC8000 or PC8500 RAM like the Gskill... that Crucial Tracer is over-priced for PC6400 RAM and at least with PC8000/PC85000 you are guaranteed a good overclock with 4GB of RAM.
