Buying a Gaming Rig for under $1000

So I need to buy a desktop PC + Monitor for about $1000 before shipping.

Here's what I've come to thus far: (click specifications for more info)

It's only $730, it has a TV tuner w/remote built in which is perfect for my dorm room. 2gb of DDR2, Dual-Core Intel Pentium D Processor 930(3.0GHz).

I throw in a $150 flat screen monitor, and $110 for a GeForce 7600GT after the rebate... comes to $990.

ORRRR

It's $790, no TV tuner so I have to get a TV tuner somewhere else for $40, it has a Dual-Core AMD Athlon 64 X2 5200+(2.6GHz), and a NVIDIA GeForce 6100.

Throw in the monitor and its $940 for the sytem.


Now here is where my dillema comes in, the dual-core AMD processor on the 2nd system is supposed to be much better than the dual-core Pentium D on the 1st system.

BUUUT, on the first system I have room to buy a nice video card where on the second one I stick with the 6100. The catch is that I can buy a DX10 Generation Video card in a few months and so my final specs for the second system will be:

AMD Athlon 64 X2 5200+(2.6GHz)
2gb DDR2 RAM
Some Fancy DirectX 10 Video Card

or I can stick with the first system, which will cost about the same after te TV tuner for the 2nd and I will get

Dual-Core Intel Pentium D Processor 930(3.0GHz)
2gb DDR2 RAM
GeForce 7600GT

2nd system will cost more and will have a lesser video card until I can replace it in a few months with a next-gen video card.

1st system has the TV tuner built in and will initially be a much stronger system at first (unless the processor difference is really such a big deal).

I want to hear more opinions before I decide on this.
