Im looking for mainly gaming and videos i have also photoshop cs3 extended and 3ds max which i dont use often..

If you get the 790GX and the HD 4770 then get a Corsair 550VX or even better 650TX. That way you have the option to add a second HD 4770 later, if you want it, without buying a new PSU.

thanks for the help aevm so i should go with the radeon 4770 which they dont have at newegg at the moment i dont think u know any other sites with as good prices?

You get 11A more (that's 11A * 12V = 132W if you prefer). Definitely a smart move for $7

I'm sure the HD 4770 will be in stock soon. It's just that it sold way better than expected and they need to hurry up and make more. Order what you can while the combos are still on. You could try other sites (zipzoomfly, ncixus, microcenter, www.buy.com, Frys, etc.) but I think Newegg has the best prices.
