Forget the hype .... the SSD will save you a few seconds of boot time and that is the largest impact you will see. While an SSD and even a GFX card are by no means essential. TAM is.
Boot times:
SSD = 15.6 seconds
SSHD = 16.5
HD = 21.2 seconds
SSDs also are great for say moving 500 GB of files from one place to another and say Opening Chrome with 100 tabs. But if you don't do these things every day, you won't have ya life impacted ina any significant way. If they budget is there, by all means put in a 250 GB SSD. If it's not an SSHD instead of a HD will costs ya like $20 and you'll lose just 0.9 seconds of boot time.
