SHOULD I UPGRADE TO WINDOWS 7????

This is my computer's spec

* Intel DP45SG motherboard
* Core 2 Quad 2.4Ghz
* 2GB DDR3 RAM
* ATI 4650 512MB ( Hoping to upgrade to a 5770)

I currently have XP.
So is it better to upgrade to windows 7 ultimate 64bit ? Will it slow down my PC?

And if i dont upgrade my graphics card is it ok to get Win 7 ultimate?

im playing games on this. Will win 7 increase or decrease their performance?

Windows 7 will have better support for the newest technologies... not to mention DX 10 & 11 support. Despite what others have claimed, DX 10 for XP is non-existent and there definately won't be DX 11. Performance-wise, you're not going to notice a difference... unless your hardware has poor XP or poor Windows 7 support. Get at least 4GB of RAM and go 64-bit.

Although RAM is meant to be cheap, atm DDR2 ram is about the same price or higher in some cases. Not sure exactly why this is, but you can still find some cheap ram from some or all sites.

The upgrade is entirely up to you. You wont really see any performance boost. Unless you install MORE than 4GB of ram. Win 7 utilizes ram more efficiently compared to win xp.

You're going to have to upgrade to Windows 7 at some point in order to use DirectX 11 that your 5770 supports.

Given that everything else on your spec list is now at the end of its life technology-wise, I'd suggest spending a little cash to give it one last hurrah - get your 5770, upgrade to 8GB RAM, get a decent CPU cooler (if you don't have one already) so you can give your CPU a good overclock and go Windows 7 64-bit.

You'll breathe a few more years of life into that system then.

Personally I'd just get the Home Premium edition of Windows 7 if you're gaming, but if there's some features on Professional or Ultimate that you like then by all means go for that instead.

If you don't have Vista, there's really no reason to upgrade....save the $$ and out 7 on ya next build

gets expensive? old RAM currently expensive compared to the prices they were this time last year.

I agree with only having 4gb of ram. I dont think OP will ever need to the use of 8gb in the life time of his current pc.

Sorry, OP has ddr3!

Having just read lastest post, double checked OP's original post and its currently 2gb of ddr3. So, upgrading ram to 8gb is worth it, plenty future proof and will also mean no future problems with finding a matching kit.

This happend to me, I installed 4gb all was fine and now that im upgrading and NEED (virutal machines and other good uses) more ram, Im paying either same or more than what I orig paid for the same ram when I originally bought just 4gb.
