Upgrading CPU/Graphics card in my 5 year old pc.

[ChernobylCow]

Hello! I have enjoyed this computer for many years. I can't really afford to build a new pc. I'm not looking for state of the art graphics. But it seems like I could get some more mileage with a few upgrades.

Checking on system requirements for games it appears that my CPU & Graphics card need to be upgraded.

Where should I start? Mostly I do not know how to choose components that my motherboard will support.

Edit: I have no idea what an upgrade budget is reasonable. Let's say $100-200.

Motherboard: GIGABYTE GA-G31M-ES2L LGA 775 Intel G31 Micro ATX Intel Motherboard - Retail

CPU: Intel Core2 Duo E7500 Wolfdale 2.93GHz LGA 775 65W Dual-Core Processor Model BX80571E7500 - Retail

Graphics: EVGA 896-P3-1257-AR GeForce GTX 260 Core 216 Superclocked Edition 896MB 448-bit GDDR3 PCI Express 2.0 x16 HDCP Ready SLI

Memory: OCZ Reaper HPC Edition 4GB (2 x 2GB) 240-Pin DDR2 SDRAM DDR2 800 (PC2 6400) Dual Channel Kit Desktop Memory Model

HDD: Western Digital Caviar Blue WD5000AAJS 500GB 7200 RPM SATA 3.0Gb/s 3.5" Hard Drive - OEM

OS: Win 7 x64

Power: OCZ StealthXStream OCZ500SXS 500W ATX12V / EPS12V Active PFC Power Supply - Retail


Thank you in advance! I will happily provide more information as needed.

Youll need a new motherboard, cpu and GPU i say scrap the build for parts and just save up for a new build.
