New Build - First Ever Build

Hello. I would like to build my own computer. I have been watching videos of Carey Holzman on youtube and he explains it very well. I found a DYI kit off of newegg.com website with these parts:

Rosewill Galaxy-01 Black Gaming ATX Mid Tower Computer Case, comes with Three Fans-1x Front Blue LED 120mm Fan, 1x Rear 120mm Fan, 1x Top 120mm Fan, Top mounted USB 3.0 Port (Model:Galaxy-01)

ASUS GTX650TI-O-1GD5 GeForce GTX 650 Ti 1GB 128-bit GDDR5 PCI Express 3.0 x16 HDCP Ready Video Card (Model:GTX650TI-O-1GD5)

SAMSUNG DVD Burner SATA Model SH-224DB/BEBE (Model:SH-224DB/BEBE)

For 586.99

It's a packaged deal. I don't think i can swap out components. Has anyone purchased a DIY from Newegg????

Would I be able to use this computer as a gaming system that would play games like battlefield 4, Call of Duty Ghosts?????
I want to keep the cost of the computer down....I dont know if i can get it to work, so....... :confused:

Any suggestions, ideas, thoughts would be greatly appreciated.
