I agree the main culprit is the vid card. Before upgrading make sure your psu can handle the card you want to run. Also a mild to moderate overclock on the cpu will help out quite a bit as well. You should be able to crank it to 3.0ghz without too much trouble.
Depending on your budget to be honest, ati 5770's are good little cards, if you can stretch to anything higher you really want to be putting it in a better system.
as Fanboy says, a decent quality psu is also required and that will support you overclocking as well
overclocking is making your chip run faster than the stated speed, you have a 2.33GHz chip, if you made some small changes and got it to run at 2.8GHz, you'd be overclocking
check out http://www.thermaltake.outervision.com/ for a rough idea of your power needs, and have a look at your psu's rating label to see what your psu actually is,
you can 'build' your system on that site including the proposed new gfx card to see what it would need with a newer card in,
if i make changes to my chip does that mean that i can change it from the screen of my computer or break open my computer and put a new one in or do something with teh chip.
Where can i find what kind of psu or motherboard i have, i cant find it at start, all programs, accesoires, systemworkset, systeminfo (im dutch so the words are prob a bit different for you)
do i need to open my computer up to find out?
np, its what were here for
ok, first off download a program called cpu-z, install it, this will give you detailed information about your system such as chipspeed,ram,motherboard etc (Gpu-z is the graphics card version)
for your psu information you will have to look inside your case to find out I'm afraid
I strongly advise googling 'overclocking' and read up on it, I really cant condense the whole subject into a short paragraph.
you dont need to remove your chip to overclock it, its usually done by making adjustments in bios, some boards are locked and dont alow you to though, so there are software-based alternatives in this case, although most experienced clockers wont recommend it, but the option is there
Ok, so i now understand overclocking and i see that my video card sucks xD
i also downloaded the program ( do you want me to take screenshots so that you can see teh specifics ? )
how can i overclock my computer? does it matter wich program i download to overclock it ?
you said i could do it by adjusting in the bios where can i find that ?
nope, thats your cpu voltage, the amount of power that is taken by your chip to function
Screenshot may help yes please
your psu number will be something like 320watt,
if you post your motherboard model, I'll see if you can use bios to overclock or not,
getting a 5770 in there will help your gaming massively yes, and is an easier option than learning to overclock,
but if you read up on it, you may decide to save for a new build, then the real fun starts
dont try overclocking your current card, you wont get anywhere near a decent result and may just blow it up
