How to decide between 3 systems...

[dcp11oc]

I put together a list of 3 systems in novatech (for a ~£600 budget)

I need some help deciding which system to get but
-can do without it until september 14th (the v. latest)
so would it be best to wait until then in anticipation of lower prices or new products
--or would it be best to get soonish so it can be up and ready/tested? ( have not built pc before )

Resolution: 1280 x 1024

Here are the 3 systems I was specing - any suggestions/alterations are of course welcomed thanks.
System will be used for games, office 07, internet.

Also, I will probably double-up the gfx next year (CF) or so if it is worth it.

Thanks for any help.

Not a big fan of your psu choice, especially if you plan xfire:

Would prefer to see you in an Antec Earthwatts, Seasonic, Corsair, or PC Power & Cooling psu . . . or one reviewed favorably by someone who looked at more than the pretty blue light.

OJ! And PC #1, absolutely.
