PC Upgrade for $200

After a recently fried mobo in my 5 year pc (which until its death, ran surprisingly quickly), I decided to of course replace the mobo. But I decided to just get a bunch of new components. I am going to get a new processor, graphics card, ram, power supply, and motherboard. I will carry over the OS, case, hard drive, card reader, monitor, speakers, mouse, and keyboard from the old computer. The components I am planning to get are as follows:

Motherboard: BIOSTAR MCP6P-M2 AM2 NVIDIA GeForce 6150 / nForce 430 Micro ATX AMD Motherboard

Graphics Card: GIGABYTE GV-R467D3-512I Radeon HD 4670 512MB 128-bit GDDR3 PCI Express 2.0 x16 HDCP Ready CrossFire Supported Video Card

Power Supply: RAIDMAX RX-450K 450W ATX12V Power Supply

RAM: SUPER TALENT 2GB (2 x 1GB) 240-Pin DDR2 SDRAM DDR2 800 (PC2 6400) Dual Channel Kit Desktop Memory Model T800UX2GC5

This is the first time I will actually be putting a computer together from scratch, so I have a couple questions.

The 4670 doesn't have a power connector and draws its power from the motherboard. Would I have a problem with that considering my cheapish motherboard and power supply?

Should I get the processor I have selected or this one: http://www.newegg.com/Product/Prod [...] 6819103272
The one I have selected has twice the l2 cache, but a 100 mhz lower clock speed, a higher voltage, and has a 90nm manufacturing tech as opposed to the alternative's 60nm.

Also, if anyone has any suggestions on alternative parts or good deals or whatever, please comment.

The 4670 should be fine.

Don't buy the CPU that you selected. Get the other one because it's newer and it draws 89W instead of 125W. In addition, the motherboard that you selected can't handle a 125W CPU.

Thanks for your help guys. I have one more question; would it be worth it to get 4gb of ram instead of 2 for an additional $13? The only RAM-intensive things I would be doing would be some gaming and possibly some photoshop and 3dsmax.

Man, at 13 bucks....just go for it.
