Worth bumping up ram on Dell XPS 2nd Gen?

[Texicadian]

Hello,
I have an old pc:
P4 3.2Ghz, 512 800FSB
250gb harddrive
Radeon X1550 (not even close to PCI/Express..but worlds better than the original 128k R350 it came with~!)
Current Ram:4 dimm, 2x512k , 2x256 (PC3200 400mhz)~1.5gb total
Am running Win XP service pack 3
Dilemma: Should I fork over $65 for this 2gb rampkg:
http://www.newegg.com/Product/Product.aspx?Item=N82E16820231047 and swap out the 256 mem sticks for 1gb sticks...total sys ram~3gb then.
OR: (very tight budget, and have never built my own..am looking at this pkg from Dell.
$669 link:http://www.dell.com/content/products/productdetails.aspx/inspiron-560?c=us&l=en&s=corp&~tab=specstab&~lt=popup
Inspiron 560 w/included 24" Full HD monitor
Intel dual-core E5400(2.7Ghz, 2MB L2, 800MHz
6GB dual channel DDR3 SDRAM @1066MHz-3dimms (think 8 gig max)
640GB SATA 7200rpm w/ databurst cache
Win7 Home Premium
weak points: 1)Video is integrated Intel GMA x4500
2)only has 1x16 PCLe slot
3)300w power supply
I mostly use current pc for home office,internet, watch a few videos/music, son plays everquest with significant lag @ 1024x768 on an ACER AL1714 monitor. Doubt I need anything more than 'budget' type pc..the current XPS covers most situations handily, but I think the memory upgrade would solve a lot of problems. The 'free' 24" monitor and win7 64 are appealing to me..and perhaps tying in a better video card similarly suggested on this site:

seems like a great 'upgrade' for us. Could use your help, due to the economy, price and $ spent is an issue.
Many thanks in advance~!

The inspiron deal is ok if it includes shipping and you need a new monitor. The next end of quarter for dell is in April; you might save an extra $50 waiting until then. I use slickdeals or fatwallet to check for pc deals. For your old pc, I wouldn't spend the $65 for a ram upgrade using xp. For windows 7, the big difference is graphics quality, but gaming is a little slower. I recommend the "pro" upgrade for windows 7 if dell offers it for $70 extra to run old xp programs. Avoid paying extra for ram at dell; that's one of their biggest profit makers.
