Buy an SSD right away, you wont regret it.
But dont buy a 256GB.
Buy 2 128 Instead and set theme in stripe
Or use theme sepratly, the cost should be about the same, if not a bit cheaper.
I got 3 ssd's bought 2 more yesterday.
1 Force GT 128
2x Kingston V200+ In stripe, i have 1.2 GB read and write xD
And for those who say stripe is a waist and that its not faster. Its not true.
Windows 7 boots a hell lot faster than on my singel Force GT + games.
