Im looking to upgrade my computer and would like to know your expertise on what i should do to be update for all games. Im a gamer and it still plays all the games but i know its getting old and want to upgrade for something affordable. Im probably gonna change my OS to Windows 7 Ultimate SINCE IM ITS ONLY USING 3GB ON XP
yikes. you definitely need an upgrade. go to cyberpowerpc.com. go to intel 3rd generation. then choose gamer series 1000. start there. upgrade the cpu to intel core i3-2120. then upgrade gpu to amd radeon hd 7770. you need to upgrade psu to 500w. that will cost around 700 for no monitor or 850 with a monitor. do not get monitor from cyberpower. there are cheaper ones that are better on newegg
No, I don't think Moosy8 knows what s/he is talking about. What is your budget for an upgrade, because it looks like you need an almost an entire system. If your current system is an off the shelf system, you can probably salvage the hard drive(s) and the power supply. The graphic card should be upgraded, but only if it's within your budget. All else, motherboard, CPU, RAM, and OS needs to be upgraded now.
FYI, you don't need Windows 7 Ultimate in order to run more than 4GB of RAM. You only need a 64-bit OS, such as XP-64, Vista-64, or 64 bit Windows 7. Unless there is a specific function of 7 Ultimate that you need, I'd recommend saving some cash and going with 7 Home Premium.
That all comes to $490. That along with the components you salvage from your current system (even the CPU cooler, it appears) should give you a hefty boost in performance. Later, when you can afford it, go for a top of the line graphics card and maybe an SSD.
