Dont get the Seagate momentus , i have one, its a ******* waste to get an Hybrid Drive I get the same speeds than my storage Sata III Drive and i pay almost the Double for this thing, Get a normal Hard Drive and Then get a cheap ssd of 60 gbs to store your Os.
The Psu is really Overkill if you are going Ivy Bridge and 7770. Get a 650w even a 550w would be Okey.
Sound Cards are always a problem for me, Either you go Full Retard and get the High end one, or get the really cheap one that gives you like a 10% boost.
Case is your Choice, Get the one you Like more get a good looking one for your eyes cuz you will be seeing it for a long, long time.
1: just get a regular hard drive
2:you need bigger gpu like a 7850 from asus
3:get a smaller psu like a xfx 650w for future crossfire. xfx i believe is cheaper than corsair and they are made by seasonic
4:for a computer case, a fractal core 3000 should suit your needs fine
5:any monitor that is 21.5 and 1080p is good.
6:for the sound card, the onboard stuff is ok for 90% of users. if you really want one, you can get a asus dx 7.1 sound card. much much better than the creative crap
7:vengeance ram is a no-no if you want to put it under a heatsink. get gskill ripjaws x memory
Thank you both for the help, need to do more searching for hard drive and SSD pairings but it sounds like a very good idea!
I've been thinking about changing the gpu but it costs so much! Thats why I thought the 7770 as it's much cheaper, with the ability of doing what I would like at the moment and then the possibility of future crossfire.
I'll change the psu to the xfx 650w, don't really have a clue about them and as you both said get a smaller one, this will be a lot better.
I won't get a sound card then, if it sounds practically the same as the internal one unless you spend a lot of money there's no point!
The case I'll probably decide last, though I like the look of the Fractal Core 3000, what I was looking for.
I'll probably change the RAM, seen a lot of that type throughout this website so must be a goodie.
The cooler was chosen by people on here, so not by me so no wonder it's good!
