Replacing my case, mobo and CPU

[Nahledge]

Newegg.com - Antec Three Hundred Black Steel ATX Mid Tower Computer Case

Newegg.com - ASRock Z68 Extreme3 Gen3 LGA 1155 Intel Z68 HDMI SATA 6Gb/s USB 3.0 ATX Intel Motherboard

Newegg.com - Intel Core i5-2500K Sandy Bridge 3.3GHz (3.7GHz Turbo Boost) 4 x 256KB L2 Cache 6MB L3 Cache LGA 1155 95W Quad-Core Desktop Processor BX80623I52500K


I have G.SKILL Ripjaws Series 8GB (2 x 4GB) 240-Pin DDR3 SDRAM DDR3 1333 (PC3 10666) and an HD 5770 graphics card. Will this all fit together?

Are those good choices for case/mobo/cpu?

This will be for gaming (WoW, Battlefield 3, SC2, Diablo 3 etc...), music, internet and movies.

Should I upgrade my graphics card as well in order to play those games?

Antec makes a good case, personally think its overpriced for what you get (2 fans, no cable routing, unpainted interior).
In order I'd go at that price range:
Sentey Black Box 4284 V2.1.
NZXT M59-001BK.
Rosewill Challenger.
But, you are the one who has to look at it, so if you dig the Antec there is nothing wrong with it.

Your graphics card falls between the minimum and recommended specs for BF3, so you'll be able to play it, just don't expect to max out any settings.
