I own ALMOST that exact laptop. A Dell Studio 16 with Windows 7 64-bit Ultimate (RTM) installed. It runs perfectly. Visual Studio 2008 runs perfectly, too. I also run the same setup on my desktop and it runs well there.
The following tools are installed and work flawlessly:
- VS2008SP1
- Altova XMLSpy 2010
- AVGFree 9.0 AV
- BeyondCompare 3.x
- CodeSmith Pro 5.1
- ReSharper 4.5.x (5.x EAP works too)
- ASP.Net MVC
- Office 2007 Ultimate
- SQL Server 2008 64-bit (2005 32-bit Express worked fine too, but I don't have that installed any longer. I am sure 2008 Express 32-bit would work as well.)
- All Modern Browsers
- TortoiseSVN 64-bit
- VisualSVN
- WinRAR x64
Another reason to go with 64-bit is because that laptop will take up to 8 gigs of RAM, and you need a 64-bit OS for that. Save yourself a reinstall and go 64-bit now :)
Other notes about this laptop that I can tell you:
The laptop starts up and shuts down in just seconds. It's perfect for Win7.
You will be very happy, Binoj!
I have more information about my setup here. Aside: I also talk about how the performance improved when I added an SSD. I'm including this slightly OT stuff because I think it would benefit you personally, as your laptop is nearly identical. Note that in the blog post I have the RC installed, but I have been running the RTM for quite some time now and it works great!
