I need to update my GPU to playback video smoother

[kona786]

Currently running a Asus Radeon HD 4350 Silent 512MB.

It's a silent GPU and that's what I'm after. I get choppy playing HD Youtube on full screen (GPU hitting 100%). Is it a Power/RAM bottleneck?

My phone also records in 1080p60 and it has a real hard time playing that back.

My system specs are:

W7-64bit
Q6600
4GB RAM
128GB SSD
Dell U2710 2560 x 1440


Can you recommend a cheap silent GPU to playback the above?

Would a Asus GeForce GT 610 2GB do?

or a Asus AMD Radeon HD 6450 1GB.


Cheers.



EDIT:



YouTube HD 1080p - Fullscreen

Google Chrome

25-30% CPU
98% GPU


Mozilla Firefox

10-15% CPU
50% GPU

Playback is very slightly dropping frames - GPU maxed out on chrome.
Firefox using much less resources but playback still not perfectly smooth.


10GB 1080p MKV - Fullscreen ~ 10Mbps

Media Player Classic

25-30% CPU
70% GPU

Smooth playback - no problems here


The above is at fullscreen - GPU is below 50% in windowed view.



Now moving onto 1080p @ 60 frames/sec - ~ 30Mbps
Shot from my Galaxy Note 3.

40-45% CPU
99% GPU even in native 1080p window on a 1440p screen.



So large MKV rips are not the problem, it's HD Flash and 1080p60 playback.

I will go ahead and take the gamble - I'm going with the nVidia as its a newer card and has more VRAM - sound good?






Cheers.

Either or should work great, I've got an Nvidia GT 510 and AMD 5450 in HTPC's and both play mkv 1080p rips in xbmc fine.

^ as above. Had a 5450 in my HTPC and played everything fine at 1080p. 6450 would be a good choice.

Have you turned off flash acceleration and seen how it is just on the cpu?

It's when you have multiple youtube videos playing and chrome running (which also uses the GPU) that things start to creak and stutter. Also multiple monitors will eat VRAM

6450 + 1gig of RAM might cut it. 512meg maybe.... 256meg definitely not. I had these problems last week and ended up just throwing in a 2nd hand 560ti into the machine. Problem solved

I tried that and for some reason this just doesn't work. I remember it working previously but not with the newer versions of flash

Thanks for providing performance figures and I must say something is just not right as they shouldn't be that bad. Maybe switch your desktop resolution to 1080p and re-run the test?

I was running a 256meg 8400gs and was also contemplating a side upgrade to a 1gig GT210 but just opted for a card with more grunt. Maybe the switch to Nvidia purevideo will solve your problems.

Ok cheers mate.

Do you think 2GB is overkill?

Man this GPU forum moves quick.

1gb should be more than enough.... Hopefully switching to fresh new Nvidia drivers should sort out your issues
