No, it is a 32-bit processor in the sense of using 32-bit virtual addresses and having 32-bit general purpose registers and ALU that operates on those 32-bit GPRs. It does feature "MMX Technology", which can process 64-bits of information at a time by reusing the FPU's registers, however, in the more common usage, it is not considered a 64-bit processor due to the lack of 64-bit virtual address space and 64-bit GPRs.
Slot 1.
That would require purchasing a new motherboard, processor, and power supply.
Pentium II
Yes. The GA-6BXC can support any Slot 1 Intel Pentium II or Pentium III processor. For the faster Pentium IIIs, you will need to purchase a "slotket" to convert a Socket 370 processor to the Slot 1 interface.

The fastest "classic" Pentium is clocked at 200 Mhz. The fastest Pentium with MMX extension is clocked at 300 Mhz. The fastest Pentium II is clocked at 400 Mhz. The fastest Pentium III is clocked at 1.4 Ghz. The fastest Pentium 4 is clocked at 3.8 Ghz. The fastest Pentium D is clocked at 3.7 Ghz. The fastest Pentium M is clocked at 2.26 Ghz. The fastest Pentium Dual-Core is clocked at 2.5 Ghz.
The Intel Pentium II was released in a Slot 1 package, while the Pentium Pro used socket 8. Adapters were available to use Pentium Pros in Slot 1 motherboards, and a version of the Pentium II was released for Socket 8.The Intel Pentium II includes MMX instructions, while the Pentium Pro does not.The Intel Pentium II has improved performance in 16-bit applications. 32-bit applications were not affected quite as much.
Possibly. "Celeron" doesn't refer to any particular processor. They are cost-reduced versions of the Intel Pentium II, Pentium III, Pentium 4, Pentium M, and Core 2 Duo. Assuming that your Celeron is based on a processor that is faster than the Pentium III, you shouldn't have any problems. If yours is based on the Pentium III, check the clock speed. A 1.2 GHz Celeron, for instance, is probably fast enough for a game that requires a 1 GHz Pentium III.Other factors, such as the graphics card of your system, may also be important.
Pentium II
The Pentium II was first released on May 7, 1997.
Basically there are two types of processors which are manufactured by two companies and they are Intel and AMD. Now there are a number of varieties available in both Intel and AMD. Intel offers Pentium Pro, Pentium II, Celeron, Pentium II Xeon, Pentium III, Pentium II and III Xeon, Celeron with Pentium III Based, Pentium 4, Pentium M, Intel Core, Dual Core Xeon LV, Intel Pentium Dual Core, Intel Core 2. Pentium Duo, Pentium Dual Core, Core 2 Quad, Intel Pentuim 2 Dual Core Processor. AMD processors include AMD Athlon, AMD Athlon 64, AMD Athlon X2, AMD Athlon Xp, AMD Duron, AMD Sempron, AMD Turion, MD Opteron and AMD Phenom 1. Moreover, there are various processors offered by various companies like Macintosh processor. In other words different processors are used for different types of technology.
