First time building my own computer, on a limited budget.

I am new to building computers, but I want something decent for gaming. My budget is very small..... This is what I have came up with so far.

CPU: AMD ADX250OCGMBOX Athlon II X2 250 Dual Core Processor - 3.00GHz, Socket AM3, 2MB Cache, 2000MHz (4000 MT/s),

Motherboard: MSI NF725GM-P31 AM3 NVIDIA GeForce 7025 & nForce 630a Micro ATX AMD Motherboard

Video card: XFX nVidia GeForce 9500GT 1 GB DDR2 VGA/DVI/HDTV PCI-Express Video Card PVT95GZAFG

RAM: Kingston KHX1600C9D3B1K2/8GX Desktop Memory Kit - 8GB (2x 4GB), PC3-12800, DDR3-1600MHz, 240-pin DIMM, 9-9-9-27 CAS Latency, 1.5V, Non-ECC, Unbuffered, Intel XMP Ready

Hard drive: Seagate ST3500413AS Barracuda Hard Drive - 500GB, SATA 6Gbps, 7200 RPM, 16MB

Case: 10-Bay ATX Mid Tower Computer Case w/550W 20+4-pin PSU (Black/Red)

I'd love any advice... or if something won't fit with something else.... I know minimal about this, so bear with me. Again, I am not on a big budget at ALL. I am used to playing games on the LOWEST graphics setting possible with lag, so I am going to be impressed by anything better than that! Haha. Thanks!
