Hello, I have a intel P4 3.0 HT, 2x1GB of dual channel 667MHz memory, 300W supply, Motherboard http://www.asrock.com/mb/overview.asp?Model=P4i945GC , which has some integrated graphic card. I would like to watch sometimes FULL HD video (doesn't need to be full screen) and I can't afford new processor and MB and RAM and Power supply. Does it make sense to buy ATI Radeon HD5450 512MB Graphics Card? I suggest that my motherboard supports PCI-E x16. What do you think?
Thank you for any advice.
The 5450 has a TDP of only 19.1 watts so it's probably not necessary to upgrade the PSU, certainly not to 500w unless you are going to re-use the power supply in a future build. I think pretty much all media players are using H.264 acceleration these days so MP4 playback will also use the HD5450 for decoding.
