Gaming New PC/How Much Will I Get?

[Berthenk]

So, I've been wanting a new PC, and to get money for that, I'm looking to sell my old one.
Edit: It's a Compaq Presario SR1859NL

Specs:

CPU: AMD Athlon 64, 2200 MHz (11 x 200) 3500+ (Socket 939)

Mobo: (afaik) Asus Amberine RS482-SB400-Amberine-00

Ram: 512 MB Infineon DDR 400 CL3 (PC3200 DDR SDRAM) X2 (Totaling 1 GB)

GPU: Onboard Ati Radeon XPress 200 (Everest (PC hardware info too) says ATI Radeon X300)

Network Adaptor: Realtek RTL8139 Family PCI Fast Ethernet NIC

And a HDD of +- 185 GB which I don't know everything about...

Please tell me if I need to give more info.


New PC specs (What the webshop says) are:

Case: Spire SP8198B - BergWind II

Mobo : 775 G31MXP-K V/S/GBL/PCIE /1600/Intel® G31 + ICH7 (Asus/Msi/Biostar?)

Cpu: 775 Intel DualCore E5300 2.60/BOX

Ram : 4 Gb Ddr II Kingston/Buffalo

HDD : 500 Gb sata II 16 mb 7200 rpm

Network Adaptor : 1Gbit

Optical: Dvd +/- Rw dual layer (Sony/ Samsung/ Nec)

Sound Adaptor (?(Sound Card?)): 6 Channel (5.1)

GPU : Intel Graphics Media Accelerator 3100 (Onboard)


All that for just 300 euros.

So, how much would I get for my old one (The first in the list of specs), and is the second one a good deal?

Thanks for the help!
