Since my HD2400 is rather quite bad recently i did some research and found that GT520 from Nvidia is quite good my question thou is would my pc handle it. I've got AMD Athlon || 64 4200+ i have no clue what the motherboard is but i know its from ASUS, and ive gathered that the PSU is 190w. For short its a S3330i from HP. Thank you in advance for you help !
The main purpose is playing casual games like FIFA and NFS but as I dont really need to have it 1080p I still enjoy them. Now to the problem with the PSU ice checked online and the biggest compatible one was 290 watts, but I guess that's no good either im not really 100% sure as to weather mine was 290 and biggest PSU 390. The reason why I thought I could upgrade was that my current card apparently is rated at around 25 watts and the gt520 is 29 watts it's the one without a fan just some big heatsink. And yes it does have PCI express slot x16, x8 and x1
any up to a gts550, or maybe a gtx560, but that would be way overkill for your system. A gt520 would be fine for your purposes. BUT there are better cards that you can get at similar price, a a 5670 would be better and use less power too.
Oh and the case is actually tiny compared to normal desktop case it's a slimline pc
or you can just take the psu out and measure it yourself. if it's somewhere around 5.91" x 5.52" x 3.39", then it's ATX and you can fit that cooler master in it. A HD5670/6670 would be a good card for you
