CORE I5 SERIES GRAPHICS ENOUGH???

1 If your gaming forget integrated graphics nothing integrated is any good for gaming unless your using a 14" seriously low resolution screen and want to put all settings on lowest quality.
2 Intels i series the graphics are integrated into the CPU while AMDs current range will be built into the motherboard so can vary, it not relevant due to answer above.
3 Get the 955 you can just set the multiplier and make it run like a 965 for free.
What ever you get try to get a Radeon 5770 or better even if it means getting an Athlon x3.

Ok just one thing choose between core i3 2100 and amd phenom 2 x4 955 and x6 for best performance in long run???????

as I stated its still the i3 2100.

For gaming such as World of Warcraft or Starcraft 2, the graphics on our 2nd generation Intel Core processor will allow you to run them at a fair level. If you are looking for better performance than what the Intel HD 2000 graphic can bring to the table you would need to add a medium level dedicated video card. Most of gamers would find that the on processor graphic wouldn’t be fitting for their needs. Now the Intel® Core™ I3 2100 is great processor for any gamer on a budget.

The HD Graphics 3000 core in the i5 2500K is more appropriate for gaming than the HD Graphics 2000 core in lower end i5 Sandy Bridge CPUs. Generally speaking, it performs better than the Radeon HD 5450. Based on the following review the HD Graphics 3000 core losses to the HD 5450 in HAWX 2 and Starcraft 2.

If the HD Graphics 3000 core in the i5 2500K could actually beat an nVidia 9600GT, then AMD and nVidia would be in serious trouble.

The phenom x 6 is not worth looking at at all as the x 4s are better for gaming and cheaper. As for i3 2100 Vs Phenom x 4 955 both are around the same price when you include a motherboard. The i3 performs better for gaming though a bit worse overall. If you are mainly gaming the i3 is the better option but there are a few reasons to consider the 955 such as:
The motherboards are better value not just cheaper but if you want more features like crossfire you can save even more on the motherboard.
You can overclock it easily by a few hundred MHz and with a cheap cooler by 800+ MHz while the i3 you cannot at all.
The true 4 cores make it better than the i3 for most non gaming apps.
The cheap i3 boards have only the most basic functions.
You can buy AM3+ boards now giving as good upgrade path as the i3 and they are cheap.
My advise get the i3 unless at least 2 of the above interest you (maybe 1 if its the crossfire one). BTW when you say in the long run do you mean for upgrades or if future games may favour one, I don't think anything I said would change either way.

Fine i agree so im heading for for phenom x4 955 but please provide me few models of am3+ asus boards

Have a look at this http://event.asus.com/2011/mb/AM3_PLUS_Ready/
9XX series boards will come out in around a month and may be better
