Hey all I have a hp pavilion a6635uk model desktop,just put a 460gtx card in it to find the CPU is holding it back to very well crap lengths. Any ideas on a possible upgrade for me please. 100 to 150 budget. This is my current mono. >> M2N78-LA (Viola)
If hp doesn't list any optional cpus, then it's a crapshoot. But they should give you a wattage limit. I had a similar board with 89 watt cpu limit. 95 watt cpus might work, but be prepared to change boards and the operating system coa if you have to change the board for the newer cpu. Oem boards are not designed for cpu upgrades, and the power supply is too weak.
No. Try it if you want, as you can run some 125w cpus. The phenom I is listed in the update list. If you can't afford a decent power supply, then you shouldn't upgrade just yet. Your original power supply is probably 250-300 watts. For a new ps, look at antec, corsair, seasonic, or enermax in 500-600 watts. For the board, msi makes the 785GT-E63 for $85 that works with ddr2 and will run the phenom 955 with a bios update. I've found remarkable deals on craigslist, if you have it available in your area. Right now a trader is selling his gigabyte board with 4 gb of ddr2 and 710 tri core cpu for $85; would probably take $70-75. You must use a micro atx board for your hp case. And a non hp board normally requires a new windows coa. Your original windows operating system is designed to work only with hp motherboards.
That's not an AM2+ CPU, your recommended CPU list does not show AM3 CPU's. It possible you could get the motherboard to run with AM3 and a BIOS update, but thats chancy. The best AMD CPU you could get would be an X4 940BE. That's a 125W part, and harder to find now.
The HP board is a budget motherboard and oem to boot. Meaning upgrades will be difficult.
I recommend that you look at an upgrade to either the aforementioned i5 or AM3+. You could get a nice AM3 motherboard, but its a dead end as AMD is coming out with a new platform. Here's a budget AM3+:
