620HX is good, but even the 520HX is more than enough for you. 620 does give you breathing room to add more things in later though.


As for the CrossFire/SLI thing:
CrossFire or CrossFireX = ATI cards
SLI = NVIDIA cards

Any P35/P45/X38/X48/5400 chipset board will do CrossFire if it has two PCI-Express x16 (PCIe-x16) slots. Note that this is not the same as PCI or PCI-X, and PCI-E comes in many variants: x32, x16, x8, x4, x2, x1. The larger the number, the longer the slot and the greater its bandwidth. You can also fit a smaller card into a larger one (e.g. x1 in x16).

For either CrossFire or SLI, you need two or more PCIe x16 slots. In the case of the P35 and P45, the x16 slots actually run at x8, but are sized x16. This is still fine for running two cards.

While CrossFire runs on any of those boards, SLI has more strict requirements. For SLI, the board must be "certified" for it. Basically, that means it needs an NVIDIA chip -- any NVIDIA board with two PCIe x16 slots should work. The upcoming X58 will have certification on a board-by-board basis, not just for NVIDIA boards.

And this would not prevent one from being able to have multiple 9800GTX+'s in SLI?
It means that the card with his cooler is so thick that it will overlap the nearest slots. But any high end card have this configuration.

If you would like to keep the multiple video card option you will need to go with ati card. Something like a hd4850 will be more than enough and in a year or two you will be able to get a second 4850 to get up to date at a cheap price. The 9800gtx+ is a great card but you will be stucked with it and need to change it when you will need to upgrade.

Over this, the 620w is a great psu and will give you some room for upgrade, even for a crossfire configuration if you don't get high overclock.

For a 19" monitor, just go with a single decent vid card and don't worry about pairing it up. By the time you get around to it a single new card will beat a pair of 9800GTXs anyway.

I run an 8800GT as well as a 9800GTX+ on a 19" and I get rediculous high framerates with all the details maxed, 16X AF 8X AA. The only game that has been pushing it is Zombie Panic Source, where it drops to 40-50FPS occasionally. Otherwise, 100-250FPS.

I am leary of NV products these days, but the 9800GTX+ is still a nice card for the money. Otherwise, I can't wait to try ATI again for my next vid card purchase. The 4870 runs hot but is an excellent price for performance. I've always prefered NV for the lifetime warrantys.

The 620W is a better unit, better now than later since the price diff is small compared to the overall system cost. That said, the 500W is more than enough.
