Enough PC for multitabling?

[Stealthy]

Cross-posted from C/T post: Tips for multitabling in SS/NL Holdem.

I am ordering a new PC from Dell on Saturday as mine is rubbish. I have an 1800 megahertz AMD Athlon XP processor. 512MB of memory with an 80 gig HD which never gets even half full. I am also lumbered with a monitor that offers a wopping 1280 X 1024 resolution. This means that I multitable 4 tables with tons of overlap as on the 1280 X 1024 setting the picture is so bad I can barely read it, so I actually use a resolution of 1152 X 864! Overlap is an understatement!

Also the PC really drags when I have 12 Party tables open (I keep a lot open cause I junp around tables a lot), PT and GameTime running. It takes ages to import the hands and lags a lot when doing so. Party closed down some graphics automatically this week cause of low memory! This has become so bad this week as it gets worse the longer I am online and after 2 hours of Poker the game becomes unplayable if I try to keep PT running! Very -EV.

So to my question is this new PC enough to allow great mutitabling with no lag?

I am now buying an Intel® Pentium® D Processor 820 with DualCore Technology (2.80GHz,800MHz fsb,2x1MB cache) which I assume will be a big improvement processor wise.

Question 1 - my memory will be 1024MB Dual Channel DDR2 533MHz (2x512). Is this enough or do I need 2048MB. I know bigger memory is better but do I need it?

Question 2 - I am buying the Dell 20" UltraSharp™ Wide Aspect Flat Panel with Height Adj Stand (2007WFP) with 1680 X 1050 resolution. 2007WFP How many Party tables will fit with no overlaps on a monitor with these specs? I want to be able to eventually move up to maybe 9 tables with 3 banks of 3 on one screen. I know I will have to resize the tables for this but is it doable without overlap?

Question 3 - I am just using the Integrated Intel® Graphics Media Accelerator 950 that come with the machine. Am I right to assume that if I am just playing poker I will not need any better as the good monitor is the important thing.

I am tring to keep the whole thing under £1,000 which is $1,850. Things are more expensive in UK than US generally so don't link to other non-UK deals as I just need to know that my money is well invested on the above specs.
