Not really. Quality of the gaming experience should include such factors as work needed to play game, ability to play game at the advertised level (witness the anger over Oblivion's graphics, for example, when players found out that at the lower graphics settings the game was flat-out ugly), reliability (should not experience crashes or memory-leaks), and code as free from bugs as possible (MoO, VtM: Masquerade, numerous others were bug-filled crap-fests), amongst others.
When these factors are included (and, keep in mind, many of the factors that I listed above are independent of the PC the game is played on, and are, in fact, on the developers'/publishers' end of the deal), PC gaming's quality is reduced significantly.

You're making a mountain out of a molehill.
If you purchase a QUALITY GAMING RIG, you will not have a bad gaming experience.
Period.
You might not have good value-for-money, but you will play the game BETTER than a console gamer.
Guaranteed. (A pair of CrossFire X1900XTs can draw resolutions of capable of powering the Dell 30" LCD panel at 2560 x 1600, that's WQXGA, baby! The Xbox 360 can't do better than 720p, which is 1280
