The P5Q Deluxe is better. It has more features, 1 more PCI-e x16 socket than the Pro Turbo (although it runs at 4x), and other accessories. However, the Pro Turbo is enough for your setup. Either of them will be a good choice, especially since the Deluxe version will surely be more expensive.
Thanx due to my mem freq. which is 667 I've finally decided to go for P5QD TURBO which i gues should be ok too.Thanx again for your help.
