Need help with picking the right headphones for Titanium HD

Hi there

I know there are a lots of similar threads and a great guide by Simca but im sill unsure if the things im considering to purchase are right for my preferences and if my Sound Card will drive them without issues.

I dont think im an 100% audiophile but i can most likely see difference between realtek HD and a proper sound card (couldnt stand the sound of RHD) so i decided to purchase Titanium HD and Logitech Z623 speakers. When i connected everything,configured my sound card and launched foobar2000 with WASAPI i got blown away by the quality of sound,it was just AMAZING!

Then my fiance came back home and i put on my Razer Carcharias and "magic" dissapeared...sound was ok,a lot better than before on RHD but it just wasnt same exciting feeling like on Z623.
I decided then that i want some proper gaming headset but reading Simca's guide and lots other threads it appeared that they are weak and its better to invest in stereo headphones + clip mic.

Now getting to the point,please help me choose proper headphones for me,here is the situation:

It will be 50% music and 50% games,sometimes a movie or tv show but that will be really rare.

Games im playing are Dota,MMO,RPG's and a bit of FPS.
Music will be Dubstep,Trance,soft electronical Music,Orchestra,Symphony and Classical Music. Sometimes Rock/Metal but thats not so often.

I want them to be comfortable so i can have them on for few hours straight,even during hot days.

I got really,really interested in Beyerdynamic DT 770,880 or 990 250 ohm but i was wondering if i my Titanium HD can drive them without issues? I do understand i wont get EVERYTHING out of them without amp but for now i want to make sure it will work on low to mid volume without any distortions and problems.

There IS possibility of buying an amp but not now,maybe in 6 months to 1 year and for now i would like to connect them directly to my Titanium HD.

Will it be sufficient? Which of Beyerdynamic DT's would suit my needs best? (never used closed cans so im not sure how they work too)

Also extra question,will amp allow me to extend cords so i can lye down on bed,listen to music while headphones are connected to PC?


I know its a wall of text,lot of chaos and bad grammar because english is not my primary language but i hope i could get some help from more experienced users.

Thank You in advance

Thanks for the link i will check it out.

Well i saw many threads where people claim dt 770 or dt 880 are working connected directly to Titanium HD card and that due to its mediocre amp they can drive beyerdynamics but wont achieve their full potential.
I was wondering if its worth to go with dt 880 for example and THD and buy amp in one year time.

Or are there any other great headphones that dont require amp and THD will be enough?

Also any good amp that You can recommend? All i know is woo audio 2 but that may be overkill.
