Quote: "an HP Pavilion with an AMD A8-3500M, and Radeon HD 6620G, 4gb ram "
this september i decided to buy a samsung laptop for 600 bucks just because i wanted to check out the new AMD A6 CPUs (somewhat worse than A8 but a lot better than i was expecting from a 1.6 quadcore) Also the laptop had some Hybrid Xfire on 6620G anda 6250 built into the A6 CPU. 4GB of DDR3 memory. (this looks pretty close to the AMD A8 HP config you wanted to buy. si i wanna share my experience based on it and hopefully my experience can point you in the right direction. ) I thought it was crap, but i liked how it looked and i was curios about the new technology as it was the first time i even saw anything with a new AMD CPU.
(infact i had no idea that AMD came out with a new line of processors)
Also the laptop looked very visually pleasing to me and all my laptops in the last 5 years were ugly and i was tired of that and wanted something that looked good.
I wasnt expecting anything much better than my crappy 1yo Acer (also 600 bucks a year ago) But this new AMD A6 (1.6 Ghz Quadcore) and the hybrod Crossfire really surprised me (does the A8 HP you want to buy have a built in graphics ion the CPU like my A6? but i think the A8 is definatley better than the A6.
I was also blown away at the laptops ability to run even modern games smoothly on medium even hight settings. (my 1 yo acer couldnt run games from 6 years ago on low settings).
The Ati drivers (i assume i have the same ones as the AMD HP on your list)are very flexible. All kinds of options with clock speeds shader speeds, sound, video etc. There is also a power/performance manager. which i kinda like. Every program you start for the first time, it asks you if you want the program to run on full power potential or battery saving mode, it does not bother you again with it, only 1 time for each program at first run.
The standard battery life in laptops these days is about 3 hours so ill assume thats how much your A8 HP is.
Finally what really forced me to question the fabric of reality... i decided to insult this laptop by installing Skyrim tearlier this week. The reacrion of the laptop unexpectadley bold by claiming that it can run Skyrim on High! It couldnt of course, but after i played around with the settings and drivers bit (nothing complicated ATI drivers are easy and great) and i managed to get skyrim to run smoothly on medium - (can get close to high without loosing perfornance) but to run FRIGGING SKYRIM ON THIS LAPTOP ON ANYTHING above low!
This Hybrod Crossfire tech is really robust and i am very happy with it. The only downside is sometimes it takes a little while to switch from 1 program to another backround program especially if you are running the first program in high performance mode. I only had this issue with firefox tho nothing else and i am really not complaining about it either, i was not expecting an actual gaming notebook for 600 bucks.
So if you chose to buy the laptop with the AMD radeon setup, you made the right choice. and the best part is that what i described about my setup on an A4 CPU should be nothing compared to your A8 laptop.
THe good thing about the AMD/ATI setup is these new mobile CPUs and GPUs are so efficient that they can crank out some real power even out of crappy hardware if used correctley.
I dont know about the intel/ intel GMA/HDA but the last time i dealt with it in detail was proboly my friends but i remembered it as being crap. so PLEASE BUY THE AMD/ATI HP LAPTOP PLEASE!!!!
LING LIVE RADEON!
LONG LIVE THE GREAD AMD!
When i got a copy skyrim,

dont hate people who rip you off,cheat and get away with it, learn from them
