1 new rig and 1 upgrade

[southpaw5000]

Here is a new build and an upgrade I would like to be critiqued. Both rigs are used pretty much for gaming, specifically EQ2/Rift type MMO's and my goal is to run them at high graphic settings with good FPS rates.
Do these look like solid builds and am I missing anything on my wifes build?

new rig for my wife it is as follows:
Rosewill CHALLENGER Black Gaming ATX Mid Tower Computer Case

GIGABYTE GA-P67A-UD3 LGA 1155 Intel P67 SATA 6Gb/s USB 3.0 ATX Intel Motherboard

ASUS ENGTX460 DirectCU TOP/2DI/768MD5 GeForce GTX 460 (Fermi) 768MB 192-bit GDDR5 PCI Express 2.0 x16 HDCP Ready SLI Support ...

OCZ ModXStream Pro OCZ700MXSP 700W ATX12V V2.2 / EPS12V SLI Certified CrossFire Ready 80 PLUS Certified Modular Active PFC

Intel Core i5-2400 Sandy Bridge 3.1GHz

G.SKILL Ripjaws Series 4GB (2 x 2GB) 240-Pin DDR3 SDRAM DDR3 1600 (PC3 12800)

Western Digital VelociRaptor WD1500HLFS 150GB 10000 RPM

And My upgrade will include:
This rig was pretty solid 2 yrs ago I am just upgrading to current technology. The rest of my system is in good condition.

I wouldnt get a velociraptor drive, you'd be better off getting 2 500GB drives and putting them into RAID 0. YOu'd have way more space and faster speeds for a lower price. And what PSU are you running in your current rig? And don't forget the OS for your wifes computer.
