I currently own a Lenova Ideapad. I bought it 2 years ago with following specs.
Core I5 2.53 mhz
4 gb RAM (2 gb + 2 gb)
500 gb Hard disk
NVIDIA geforce310 video card
Windows 7 64-bit OS
I notice when I work with large RAW files in photoshop cs4 it slows down. there seems to be a lag when I'm using healing brush tool, blur, dodge etc. If I'm not working with raw files changes made on the image are smooth.
What should be the correct hardware / software for optimum performance in photoshop or any other photo editing software for retouching RAW files?
Thanks in advance.
