I recently bought a computer which I will primarily use for work and web browsing, but would also like to play the occasional game. I would like to know if upgrading my psu and processor will help if it's possible and what to upgrade to. My system information: Operating System is Windows 7 Ultimate 32-bit System model is Packard Bell Bv Istart Processor: 3.07 Gigahertz intel pentium 4 Somebody has already told me the following. 'Your motherboard has a PCI-e 16x port. It will accept any almost any graphics card out there. But your CPU will bottleneck anything that will play games decently. Also, the PSU with these pre-built PC is often of quality just enough for the system in question. You won't be able to put a mid-range graphics card in it, even previous generation ones. If you want to use this PC for a little gaming, a Radeon 6570 will do. It does not require additional power connectors. It might still be more than your CPU can handle, but its around the lowest card you can get. Still, if you can, you can built a nice little gaming PC that can run modern games for around $600.'
