Why do I get such terrible FPS?

cweggleton · Dec 12, 2013

Hi Everyone,
I am currently running a FX8150 with an ASUS M5A78L-M/USB3 board along wtih a 2GBDDR3 Radeon HD 6450. I have 16GB of DDR3 RAM in the machine also. My question is that when i play games (for example wow) i get no more the 30fps. I am sure this should be way more than this. Has anyone experienced the same problem or could anyone give me some tips as to what to look into? My PSU is 450W and I am thinking it may be throttling the system at the moment but I don't want to go spend £50 on a new one if I don't need to. Any advice would be great.

Regards

Chris

You must be joking... Your Radeon HD 6450 slows everything down, it's a really low-end card...

daswilhelm · Dec 12, 2013

first reason is the 6450 is not a good card for gaming, it is very weak. another reason is the x1xx series of amd cpus arent good for gaming either.

the 6450 is the first thing i would upgrade and then look at your cpu later.

The 6450 is a very low end video card and won't play games very well. Depending on the make and model of the PSU it may need to be upgraded if you get a better GPU.

Daswilhelm has it right about the graphics card; the HD6450 is a HTPC card, not a gaming card. The cheapest gaming card I'd buy is a GDDR5 version of the HD7750. You should be able to find a HD7770 for not much more though.
The FX-x1xx AMD CPUs are indeed under-performers, but are still reasonably capable. That's perhaps a more long-term replacement, but the graphics card should be replaced first. A quality 450W PSU should have no trouble with a midrange card on up to a HD7850 or GTX650Ti Boost. What is the brand and model of your PSU? Does it have a 6-pin PCIe cable (currently unused)?

yeah... all of the above... it's like asking "why doesn't this yaris do 200kph, it's got an engine". Upgrade tha gpu!

Hi Everyone,
yeah I was thinking this might be the problem. It was a last minute thing as the person who sold me the pc didnt have a gpu install and only had the onboard. So if I was going to spend around £100 what would you recommend?

Thanks
Chris

Assuming the PSU is decent, you should be able to get at least a HD7770 for that, maybe a HD7790 or R7-260X.

So something like this? http://www.ebuyer.com/541122-xfx-radeon-hd-7770-graphics-card-1gb-pci-express-3-0-x16-fx777aznj4-fx-777a-znj4

I may get a new PSU also because I think maybe the load of that card plus the 8150 might require some more juice. Any recommendations on a decent PSU say 700W plus?

Thanks
Chris

I recommend a Seasonic, Corsair, or Coolermaster brand PSU. Stay away from OCZ.

daswilhelm · Dec 15, 2013

700 watt is way overkill. if you're planning on running the 7770, you barely need 400w if your power supply is a decent brand. can you tell us your psu make and model?

TheTechGamer · Dec 15, 2013

The 6450 or all 450 models are the lowest end cards, they don't play games, just web and casual usage. I recommend a HD 7770 or above to start gaming

Onus · Dec 15, 2013

Most low-end (i.e. all but a very few) CM PSUs are only a notch or two above junk. They are overrated and/or missing protection circuits. Their newest ones are now made by Seasonic, but they're not the cheap ones either. On a budget, the Antec EA-380D or VP-450 is strong enough for any graphics card with a single six-pin PCIe connector.

Onus :

This is correct, however their newer PSU's are excellent. If the OP only wants a low end PSU he should just stick with the best brand out there... Seasonic.
