I have doubts about changing motherboard?

[Pedro Miguel]

I have an intel h61, and I'll buy a radeon 7870 ghz oc edition.
My PC has an i5 3450, 4gb ram and 1333mhz(i want to put more 4gb ram 1333 to stay with 8 gb ram 1333).
I wonder if the asusp8b75m buy this motherboard, I need to change the desktop to be functional motherboard.

this cooler(http://www.pixmania-pro.com/pt/pt/04750361/art/cooler-master/fonte-de-alimentacao-pc-gx-550-w-rs-550-acaa-e3.html) is suficient to my future desktop?

And i want to now if with this desktop i can run crysis 3, battlefield 3, assassins creed 3, everything on ultra in 1920x1080 full hd

thank you,

If you buy a new board ( asus p8b75m ) then yes you'll need to unplug/takeout all other components that are connected with your old motherboard, then take the old motherboard out of your case, put in the new board and put/plug all other components/cables back into their places again. You will also need to reinstall Windows after changing the motherboard.

The Cooler Master PSU you picked is more than enough for your new system with a 77870ghz installed.

As for gaming, all titles but Crysis3 could run on ultra 1080p without any major problems ( you need at least a gtx770 to run Crysis3 on ultra 1080p smoothly, and it's way over your budget. Better stick to high settings for this game only ).
