I would recommend the SR60is, but with a strong note that they are "close" and doesn't come with a wide stage that games really "need". Dimensional sound queues will not be as prominent with these cans. Comparing the SR80is to my AKGs, I find that while the sound is better in the Grados games become a lot more enjoyable with the AKGs, especially games like Battlefield 3 where the dimensional sound is very potent.
Perhaps you can strike lucky and find the Sennheiser HD598 for around ~€140. They have dropped to 1350 SEK here in Sweden at least.
Others to check out would be the AKG K601 or the ATH-M50s around ~€100. The M50s are closed and offer fairly heavy bass but still a good stage. I'd say they are very "fun" in that regard. The K601s is more open and flexible, but lacks that "oomph". Afair, they are very similar to my K242s.
