MacBook Pro 15-inch 2.2GHz Intel Core 2 Duo

I bought a Refurbished MacBook Pro 15-inch 2.2GHz Intel Core 2 Duo from Techrestore.com yesterday.
exact specs
* 2.2 GHz Intel Core 2 Duo processor with 4 MB shared L2 cache, Mac OS X v10.5 Leopard
* 1 GB RAM (two SO-DIMM) 677 MHz DDR2 SD-RAM (PC2-5300), 120 GB 5400 rpm Serial ATA hard drive, slot load 8x Super Drive (DVD±R DL/DVD±RW/CD-RW
* 1 FireWire 400 port, 1 FireWire 800 port, 2 USB 2.0 ports, ExpressCard/34 slot, DVI output with support for VGA
* Built-in 10/100/1000BASE-T (Gigabit); built-in 54 Mbps AirPort Extreme (802.11n); built-in Bluetooth 2.0+EDR
* 15.4-inch (diagonal), 1440 by 900 resolution, Matte TFT LED widescreen display with NVIDIA GeForce 8600M GT 128MB graphics processor
* Support for up to 4GB of memory
* MacOS X Leopard with iLife

I loaded it with 3gb and a 1yr warranty. It is the 2006 version. I paid $1054.00. My question is, am i getting a good deal? Is that model antiquated now? I plan to use it for Adobe suite. Would I be better off getting this configuration from apple? "
