CUDA performance on gaming nVidia cards is a joke now that its artificially limited. If you want CUDA, you are pretty much limited to an nVidia Quaddro. Supposedly Corel is moving toward full OpenCL support, which means that AMD Radeon cards would be a nice option when they incorporate OpenCL.
That being said, you aren't left with too many good options in this case as Quaddro cards are expensive and there isn't OpenCL support yet to use an AMD Radeon with Corel.
So, that basically leaves you with upgrading your CPU. If you are on an older socket, that may mean upgrading your motherboard and memory as well.
Could you list your computer specifications so that a more educated recommendation can be made? Please include brands and model numbers for the following (CPU, GPU, RAM, Motherboard, PSU, HDD)
Sorry. I mean I am a student at school and editing videos is a hobby. I don't use my computer to edit long movies, just short videos.
I am not an American (Vietnamese) and please don't laugh at my computer.
-E5700 <---- I will get a quad core, maybe Q9650, Q9550S or Q9505S
-Nvidia GT 210 <---- This is why I am saving money.
-Ram 4GB DDRIII
-ASRock G41 Vs3
-A stupid "Made in China" PSU that says: 250W (+110W max) ( I calculated the power consumption and if the video card wattage is under 65, everthing should be fine)
This PC is a joke, right?
I don't have money for a new mainboard.
I will get a quad core first. I hope in can buy it for about $120 (but not in dollar of course)
Then I will get a Video card. I may have enough money to buy a GT 640 OR a 7750. The 7750 outclasses Gt 640 BUT it doesn't support CUDA ( WHYYYYYYYYYY ). However, I must wait until next year. By then, the new 700 seri of Nvidia should have come out. So should I choose an expensive Nvidia card OR get a AMD card and wait for a miracle such as Corel supports OpenCL.
