For whatever reason, I grew up fearful of spending money. It's not the worst habit to have, but it takes the fun out of every purchase.
I had an Athlon 1400Mhz with 256 RAM and a Geforce 2 GTS for 8 years before I got my current rig. But ever since buying this, I've been thinking about upgrading or actually upgrading on a regular basis. It's a horrible feeling, throwing away money like this. If I got a GTX 595, what's that gonna get me? 40FPS in 3dmark 2011? How good is that gonna make me feel?
