With hardware decoding on the GPU, 1080p is fine but you need the right codecs installed that support it. And of course the right GPU!I hope you are not planning on 1080p with a P4 2.8GHz. Judging by what I have seen, 720p is playable but not 1080p.
720/1080p h.264.mkv playback with P4 3.0ghz possible?
Some of the comments seem to suggest that 1080p is possible depending on the GPU used. Can someone clarify this?
Still yet I agree with ikesmasher, it's time for an upgrade in platforms.
Upgrading processors is the reason you would need a new motherboard. Which would also mean in your case, you need new memory modules. And unless you have an operating system that is transferable to a new system, would mean you need a new operating system to go with the new PC. I do hope you have an ATX case otherwise you would need another case as well.I was thinking get a New mother Board , with PCIe expansion slots , fit my old p4 processor in it.
