As Chris said, memory is going to really help you with graphics. And make sure your scratch disk isn't nearly full, that's a common problem I've seen with people complaining of Photoshop in particular being really slow.

I use a Dual Core MacBook, and find Photoshop and Illustrator run nice and smoothly.

But i don't know which is best. I think that Celeron is old technology and it's better to choose another processor.

I basically want a processor which will handle all aspects of a computer, basically everything a computer does, but i want it to be able to handle everyday tasks without any problems. Such as watching videos, playing games, and running multiple applications simultaneously without any problems.

Celeron processors are for small businesses or office use but are still being made today with new technology. They actually can be quite dependable but It sounds like you need an "entertainment" pc which I consider to be middle of the road.

You don't need a high end pc for what you are talking about but you don't want low end either. be sure to get at least a dual core processor - a triple or quad core is much better - AMD makes really good quality processors and inexpensive compared to INTEL.(also good but much pricier) AMD has never let me down - back when they were making pc's I had 2 and after 5 years they were still going strong with no problems - unlike the 2 HP's I purchased in 2009....both had problems from day one - eventually, 1 went caput less than 2 months after 1 yr warranty ran out.

I am also not in favor of Windows7' I think it's awful compared to XP. It's all about visual (customizing desktop) ..... but NOT about performance. the terminology used for specific apps, procedures or settings have now been grouped together calling them different names and you cannot access or customize them like before. there is no Windows7 help program/menu. All help must be accessed thru online support at Microsoft. But their search query is messed up so you have to go to the forums and search manually for what you need....and theres more...

There are multiple bugs and critical errors with Windows7 causing a lot of headaches with many people. i.e. hangs, boots & shut downs taking too long, sudden crashes or reboots right in the middle of working, some applications and accessories are inoperable, services stop at any given time and the notorious BSOD.

Microsoft has programmed their tech help to initially advise you the problems stem from your hardware but that's ridiculous when you look in the forums & see how many requests for help there are with the multitude of hardware brands & models across the board. Once you have convinced them thru a series of posts telling them that you've already run virus/spyware scans, tried mulitple setting changes or fixes They will take you thru some long & complicated procedure fixes to which 85% have no results. Its beyond ridiculous.

Apparently Microsoft has just released an "SP Fix", but I've read it doesn't even address the critical errors that everyone is dealing with. Personally I'm too scared to install it for fear of it screwing something else up.

As soon as I have time I'm going to look at trying out Google Chrome...

So my advice for what its worth.....is get yourself a middle of the road pc/laptop with at least 4 gigs of ram and at least a dual core processor with any OS other than Windows7.

If you can afford it - get a MAC - they never break down and rarely have virus issues.

But i like amd.

When I was at Games Convension in Germany. I saw a really big high end Computer!
It calls "höllenfeuer 3".
