As for the SSD card, you'll only enjoy it's speed for short period of time.
It's still not fully completed and over time, SSD loses it's performance.
If I were you, I'll go ahead buy either 500GB or 1TB spin disk for about $50 - $80. And with that extra money invest it on ATi's 5870 card. this card is almost on par with GTX 295 also supports dx11.
That's just my thought of improving your pc performances.
And you'll love me hard core for making that decision for you.
