Hrmm, so it looks like you have an old AMD processor in there... I can't tell exactly what kind (probably a Sempron or Athlon 64), but regardless it's definitely not desirable. If you plan any sort of modern gaming, it simply won't do. I have a hunch that you have a
socket 939 processor. All socket 939 motherboards are compatible with their corresponding processors. That said, socket 939 processors have been all but abandoned in favor of the newer, faster, more efficient
socket AM2. If you want to use a socket AM2 processor, you will need a socket AM2 compatible motherboard. So you have some options here.
It looks like you have 1 GB of RAM, which is fair for XP, but not for any sort of modern gaming (even games 2 or 3 years old may long for more RAM). I can't determine what kind of RAM you have from what you posted. You may have
DDR 3200 RAM, which is the fastest of the old DDR RAM.
DDR2 RAM is the standard nowadays.
DDR3 is in ridiculous high-end systems and isn't showing any sign of becoming mainstream anytime soon. Unfortunately, DDR, DDR2, and DDR3 are all incompatible with each other, so make sure you figure out what kind of RAM you have before attempting to upgrade.
That graphics card is definitely not up to any sort of modern gaming. Luckily, great performing graphics cards have gotten incredibly cheap; that is, if you have a motherboard that supports the now-standard PCI-Express. Many old mid-range computers used AGP slots, which, suprise surpise, are no longer supported by graphics cards manufacturers.
So now we've identified which areas should be upgraded (haha, basically the whole thing). We do need more information before we can make any serious recommendations. Try to figure out:
What socket motherboard and processor you have (they will match).
What is the fastest RAM compatible with your motherboard (DDR 3200? DDR 2700?)?
Do you have an AGP slot or a PCI-E x16 slot (this is where the graphics card goes... the PCI-E will give you much more flexible and cheaper options)?
To find this information, you can use the trial version of a software called Everest. Find that here.It would be very useful for us to know how much money you intend on spending on these upgrades so we can give you the best advice. If you are looking at several hundred, it may be in your best interest to purchase a new motherboard + CPU + graphics card + RAM. This will essentially give you an entirely new system, but it is often the best option with old computers. If you are looking at less than a hundred, then you'll have to make marginal upgrades. You should also consider that upgrading a motherboard means gutting the whole system and replacing the RAM, video card, and processor. It's not easy if you don't have any experience doing it. Replacing a graphics card or some RAM or even a processor is very easy and straightforward in comparison to a motherboard change.
