Although I very much enjoy spending my spare time editing my high definition video footage and processing large RAW format photos, I find myself becoming increasingly frustrated with the performance of my trusty old P4 when performing such intensive tasks as previewing my videos or processing just about anything, so I feel that now might well be the time to invest in some new hardware. Usually I would just go out and buy the best parts I can afford, but I have been away from the IT front line for some time now and I don't know what is good anymore, which is where you guys come in. My budget isn't huge so I can't afford to buy a PC named after a character from Norse mythology, so I need to know what I need to prioritize when I decide where to spend my money on.
My main questions are:
1 - Intel or AMD?
2 - NVidea or ATI?
3 - What will bring the most performance benefit for video & photo editing: Video RAM / system RAM / processor Cores / GHz?
Clearly I would benefit from all of the above, but the budget forces compromise. I am not a PC gamer -I have a playstation for that- so I don't need anything specialized towards gaming.
Any suggestions would be greatly appreciated.
Thanks as always!
