Current vista out now: NO. It barely supports Office and you cant install any of your old programs (say goodbye to all ur games inc CnC3) and u cant network to Xp pro or older.
Stick with XP, better than being gay
Um, CnC3 works fine on Vista 32-bit. Doesn't work on Vista 64-bit.
In all honesty, Going for Vista now isn't going to hurt you too much. Pretty much most drivers are available (albeit a little buggy still) and you've got DX10. If you go XP, you're going to be limited to DX9 (officially - apparently a DX10 wrapper may be available sometime), and you'll have to buy Vista later on to enjoy the benefit of it when it becomes mainstream. Look, you're going to take a performance hit with Vista, but if you're getting a decent machine, you're not really going to notice.
As for not supporting Office? Well, it seems to work fine at my office. Granted we're using Vista Enterprise, but I'm not aware of any problems.
Bleeding edge comes at a cost. Is Vista worth it, I can't say, but as much as I like XP, Vista WILL get going, and it WILL become mainstream Windows, so you may need to suffer a little bit now, and be more prepared that us XP guys later. I use XP64, which took almost 2 years to get a lot of basic tools (Daemon Tools) to work, and sadly it's still not fully supported. Do I regret using it? Sometimes, but I can play some games in 64-bit mode, and they look AMAZING! I can only imagine what DX10 games will look like, compared to the lowly DX9 version. DX10 games may be nowhere in sight now, but come Christmas, I can almost guarantee you'll see a whole bunch of them.
Simply put (in my opinion) :
XP - Best for the next 6 months
Vista - Best for the 4 years after that.

Also I am planning to network it to my old XP Home and will that be an issue if i use Vista
No issues.
One thing I didn't look at before writing this long post, was what machine you were getting. DX10 is of no use to you, as you're getting a Nvidia Gefore 7300 LE which is pretty much bottom of the line DX9c card. I would say you'd probably notice the performance hit of Vista, so I recommend XP, ONLY because of your GPU. Maybe save for a few months, and wait for the mainstream DX10 cards (Nvidia Geforce 8600/ ATiAMD 2600). The choice is yours.
