Your IGP will be just a lil better than your old 9800 pro. Those games will likely be playable at low resolutions with modest settings but not well. A good cheap card that would be much, much better is the HD4670.
I got it today, the box says it acheived 28003dmarks with 128mb sideport memory and overclocking. I believe it comes with sideport memory, so I'll have to play with the clocks and find out. SUrely the cooling isn't too good on those things though, I couldn't find he chip on the mobo anywhere, i assume its under a heatspreader but there are quite a few.
It is part of the chip that is under the heatsink that is directly below the CPU socket (or directly above the PCI-E slot, depending how you want to look at it). That one does have pretty good cooling. My 3200 easily OC'ed to 900MHz and probably could have done more (from 500MHz stock). I think that one starts at 750MHz. It should do ok.
Sorry to necro this thread > but im about 24 hours away from having my new rig up and running. Though I fully intend to purchase a high end radeon card in the future, for economic reasons ill be running the hd 3300 integrated chipset with 2x2g ddr3 1600 and a 955 BE on a 790 mobo for at least a month or two. Also I'll be running ubuntu/red hat (choice, not economic) im wondering what sort of performance i can expect running wow via wine. Also what opensource drivers would be preferable? or does ati offer proprietary driver support for 64 bit linux? I would like to avoid running 32 bit at all costs as I do a fair amount of recording and video conversion and the like, i want to cap over 4g of ram, and i am willing to accept windows 7 ult 64 as a necessary evil. I might take this to the ubuntu forums also but I do appreciate any feedback!!
update. Admittedly I am no expert with a linux based os, but after not but complications and headaches for several reasons like driver support, audio issues etc, I took the plunge and got w7 64. WoW? yeah this thing will play wow pretty damn well next to my old 915gm. It will play 360 games for pc(which is groovy cuz I have a ps3 and now i can get my ME2 on), older games like ut 2k4 and half life 2/portal at max settings. I still intend to purchase a high end graphics card but for an intermediary step on a $125 board this igp is pure sex. I also understand that the hybrid technology will boost the effectiveness of any compatible graphics card that you install in the future, meaning the igp isn't wasted after you upgrade I will say again that I don't know much, but I love this igp and I'm glad I got an os that realizes its full potential. As someone else said, with a decent processor and ram backing this up, the 3300 is a great temporary solution. Of course it looks like you and I have already purchased and are using this igp, making any further speculation fairly moot, let's go play some games and let this thread die.
World of Warcraft
hybrid works only with Radeon HD 2400 and 3400 series cards, u cannot use it with lets say hd5770 or other newer cards
